Have you ever had a mouth-watering pizza ruined by an inaccurate infrared thermometer? That’s like a punch to the gut, mate. Pizza ovens can go from 400F to a blistering 900F, and you only have 1-2 minutes to get that delicious pie out before it turns into a burnt crisp. So, you need the best infrared thermometer for pizza ovens to save your bacon.

However, going through specifications like emissivity, distance-to-spot ratio, optics and lens, and thermometer type may shake your buying.

Best Infrared Thermometer For Pizza Oven

Just picture this; bearing long preheating sessions, your pizza comes out burnt or half-cooked? You love mushrooms, but they are now indigestible; you love crispy crust, but it’s burnt now. Misery!

This is where a heat sensor gun, aka infrared thermometer for pizza oven can save your day.

It’s a truth that many big pizza oven brands miss out on built-in thermometers. And ovens that come with a built-in thermometer, either they are expensive, or the temperature accuracy is dubious.

Yes, we know thermometer accuracy is the key, and one definitely can’t compromise on that. So, 1000’s of “accurate IR thermometers” claiming themselves “Best,” we have narrowed down some of the finest performers in the market. Testing out in our lab, below is our experience with these gadgets;

How to Buy the Best and Most Accurate Infrared Thermometer

Out of hurry and before you ask us, the “Ah, wait is killing me! Tell me, what is the best infrared thermometer out there?” Hold your horses, mate! A best temperature gun is related to your goal. Any top-rated infrared thermometer can be impractical if it doesn’t align with your purpose.

So, before you randomly jump on any IR thermometer and say, “Yeah, this is my boy,” we are listing some of the very basic math you should do before you finally dance on a buy button. 

How to Buy the Best and Most Accurate Infrared Thermometer

Thermometer and Lenses Type:

For types; there are infrared and Probe Thermometers. The probe is mounted thermometers that get hinged internally in the oven. They are accurate, cheap, and the most basic type. This can be a viable option, but if you want features and advanced usability, an Infrared heat sensor gun is the best choice.

On the second side, many thermometers specify their lens type, which may puzzle your mind. Most commonly, there are 3 types of IR lenses,

  • No Lens
  • Fresnel lens
  • Mica Lens

No Lens: Most basic type, Good for cold environments, Bad for long-distance temperature measurement, good accuracy, sharp detection with lowest resting period, not durable

Fresnel Lens: Good Accuracy, suitable for most of the food and restaurant industry, takes some seconds for acclimation when temperature changes, usually comes with laser guide, inexpensive and reliable, good practicality

Mica Lens: Industrial grade lenses made with mineral glasses, extremely accurate on temperature changes and high temperatures, expensive and slightly hard to manage, delicate and long acclimation periods.

You can take an idea of which lens would be most practical for you. If your goal is ultra-affordable IR thermometers, note down, it shouldn’t be a no-lens thermometer.


This may be a hard thing to understand for non-techies, but this factor flaunts the greatness of the IR thermometer. Masses release radiation. An IR thermometer, with its temperature-detecting sensor, turns these radiations into electronic signals, and you get to know the temperature of these masses.

Now every substance poses different emissivity; your infrared temperature gun should comply with this. For example; with water having 0.92-0.96 emissivity, copper with 0.60-0.95, Steel – 0.07-0.65, and Aluminum with 0.4-0.09; you should choose a best IR thermometer with multiple emissivity settings so you can measure temperatures for different surfaces.

Multiple emissivity devices usually have a bit of premium. In that case, if you don’t want to spend extra money, choose a thermometer with an emissivity between 0.95-0.98. This range is appropriate for materials like paper, plastics, wood, and textiles with high emissivity values.

Distance to Spot Ratio:

The second most technical factor while choosing a high-temperature pizza oven thermometer is the distance-to-spot ratio (D:S). In simple words, the D:S formula determines the precision and accuracy of the temperature gauge. For 10:1, it means the IR thermometer will measure 1 inch of a targeted surface when the user stands 10 inches away.

The higher the spot ratio will be, the higher will be the chances of getting variable results.

Here again, your purpose will greatly impact the choice of your best infrared food thermometer. For small portable ovens where fire flames are less likely to expose and may not hurt a person, a low D:S thermometer can even work. However, if you have a bigger wood-fired oven or BBQ grill with open flames and going closer may risk your health, you should use a bigger D:S thermometer, like a 20:1 thermometer.

Temperature Range:

A huge chunk of the pizza oven family ranges between 400-900F. So, in that regard, you must see the specs of the thermometer on how far it can go. Like Ooni, Bertello portable ovens range even 950F, so you must choose a thermometer that can pass 1000F to avoid errors on your temperature screen.

Well, Well, ….. Well! Apart from these points, you must consider Accuracy, batteries, and budget factors to align your purpose with the right device. There are hundreds of IR thermometers with more or fewer features; you can prioritize these features as per your requirements but don’t forget to consider these mentioned factors.

We perfectly know some impatient souls won’t find it easy to go down in each product to find themselves a best pick. So, here is a quick overview of this detailed buying guide. 

Out of all these best infrared thermometers, we picked AmazonCommercial 66IR360 as our WINNER. This IR thermometer doesn’t enjoy a humongous brand value like Fluke or Etekcity, but in terms of performance, it gives Goosebumps due to the extreme abundance of features and specs under a reasonable budget. From great optical range to temperature range, it beats many expensive gadgets. However, if you are a guy who doesn’t want to step even an inch back from strict accuracy, FLIR TG54 is our Runner-Up and would be best to consider in that case. The only reason it didn’t make it to the top spot is the higher price. 

Lastly, you can check other products in our list as per your requirements.

1. AmazonCommercial 66IR360 – Overall Best Thermometer for Pizza Oven


AmazonCommercial 66IR360

Why Do We Choose This: For a 20:1 optical range thermometer, how much are you ready to shell out? 100 bucks, 150 bucks? Definitely prepare 100+ bucks or even 200$ for such a device. Then if you ask for a special exception, there is Amazon commercial 66IR360 breaking all the rules, having a bombastic set of features at the most competitive pricing. With a 20:1 optical range, adjustable emissivity, snappiest 150 ms response time, and most prolonged temperature range -58F-1800F, it’s just unbelievable to get all this under a 50$ budget.

Who’s it For: HVAC systems, automotive sector, refractory kilns, wood-fired ovens.

Who Should Avoid It: Brand Conscious Users,

The Best Selling Points of AmazonCommerical 66IR360:

  • An Amazing Value to Money: Considering the abundance of features and specs, it covers the most competitive pricing in the market.
  • Most extensive Temperature Range: Where many of the Best IR thermometers fail, this takes the lead with the broadest temperature range.
  • Adaptable Emissivity with Quickest Response: We have Fluke 62 Max+ with 300ms response time, but it costs 100+ bucks. Amazoncommercial does the purpose in half the time and pricing.

Design and Build Quality:

Similar to other temperature guns, it also poses the same design and structure overall. However, the materials seem off-standard compared with many premium thermometers like Fluke 62 Max+, Flir TG54, and Extech 24514.

Now, terming off standard doesn’t mean it isn’t durable or has cheap materials. That said, Leonard reported that the feel and shine and feel of the product were a bit off than the premium brands.

The manufacturer didn’t mention its durability against heights. However, we reluctantly did a drop test from 1m and 1.5m, and it sustained those shocks well. We also didn’t have any info about the water and dust test, so we didn’t perform those tests to avoid any damage.

But overall, the design and usability section isn’t very fancy or advanced, yet it maintains good usability and practicality in every type of scenario.

AmazonCommercial 66IR360

Performance and Temperatures:

We may not have enough stuff to comment on in the design and build quality department. But truthfully, when we explored the performance area, Brian said, “Wow, the real deal is here.” First of all, seeing the price, we double-checked if it was really a 1800F range high-temperature pizza oven thermometer.

And Yes, it ranges from -58-1800F, which is top of all the best-infrared thermometers we have tested so far. Can any other IR thermometer handle that much heat? So far, there is no beast in our listing achieving that milestone. Moving on, the second most eye-opener feature was adaptable emissivity, rendering the wicked fast 150ms response. We had the Quickest in the form of Fluke 62 Max+, featuring 300ms, but Amazoncommercial thermometer leads this department.

Yes, one may argue it doesn’t table a difference between 150ms and 300ms, but it’s a matter of efficiency for many pizza and tech enthusiasts.

Anyways, the Amazoncommercial greatness doesn’t end here. Finding ourselves in a greater sphere of wonder, the 20:1 optical range was another thing to watch. And combining this feature with perky accuracy took all of our appreciation. Though the manufacturer states it is +/-1c accurate, in our testing, it practically denies these claims slightly and it was more like a difference of 5-8F.

But hey, who’s counting? As long as it gets the job done, right? While this isn’t a big difference, you can still have fantastic pizzas while relying on this pizza oven thermometer gun.

Overall, the huge specs and abundance of every feature exceptionally put this gadget ahead of many premium branded devices.


  • Inexpensive and provides great value for money
  • A very extensive temperature range expands its utilization
  • Quickest response makes it viable in highly sensitive situations
  • Trustworthy accuracy
  • Excellent Distance-to-spot ratio
  • Gives you an alarm for different notifications


  • Feels a bit plastic than other premium devices
  • Though our device came complete fine, few users report minor scuffs on screen

Alternatives to AmazonCommercial 66IR360Etekcity Lasergrip 800

Truthfully, everything in this gadget is in great abundance, and that makes it very unique when it comes to pricing. But if you still lack some budget and such abundance isn’t practical for your Etekcity 800 Lasergrip 800 might be the right thing to consider for under 30$. The 1382F highest temperature range, 16:1 D:S, and great 14hrs battery life would be another great set of features for you. Though it lags a bit in response time, that wouldn’t matter if you prefer accuracy.

With that being said, you’ll also have to make a little compromise here with fixed 0.95 emissivity. But we can’t complain as we get what we pay for.

2. Fluke 62 Max+ – Best Weather-Resistant Laser Thermometer


Fluke 62 Max+

Why Do We Choose This: When it comes to measuring instruments, how can we overlook Fluke? And for this device, it’s the most advanced in the Fluke lineup with a multitude of features, including better accuracy, D:S range, and speedier than its younger brother and previous series Fluke 59 Max. With multiple features and build quality certainly to admire, we loved the adjustable emissivity and backlit during lowlights for supreme usability. Though it’s a pricey one from all of the Fluke mini temperature thermometers, the NIST certification can put your trust in its accuracy department.

Who’s it For: For home chefs, Industry workers, Intermediate users

Who Should Avoid it: Budget Users, Medical purposes

The Best Selling Points of Fluke 62 Max+:

  • Excellent Build Quality: The plastic body feels tough, that’s why it is indestructible within a 3m fall, and the IP54 rating makes it able to fight dust and water conditions.
  • High Accuracy: NIST certified and much improved from its little brother’s previously 1.0% accuracy ratio, empowering it for a worthy upgrade.
  • Much Faster Acclimation: Though the last 500ms responsive was much quicker, it’s much swifter than its older model.

Design and Build Quality:

With tons of pizza oven thermometer guns available in the market with almost similar complaints of breakage and unreliability, the Fluke 62 Max+ seems like an exception. Though it’s a hard plastic, the overall composition looks sturdy, and you actually have a feel of holding a quality gadget.

While it’s only 9 ounces, the grip design is very much decent for small-medium size hands. However, this may not be good for oversized hands or people suffering from arthritis. Our own Leonard, with his smaller hands, found the grip to be a bit sticky but not too uncomfortable due to clever design elements. Through his comments, “The grip is actually feeling gluey to my hands and with the right positions of my fingers due to design elements, it’s not making me feel weird.”

Anyways, Fluke 62 Max+ poses excellent usability with a good backlit display during low lights. Additionally, we didn’t test it against the marketing claims of safety against 9 feet fall, but we tested a light drop from 1m, which didn’t catch any scratch. But then, we tested it against heavy water splashes, and it remained intact as per IP54 claims.

Overall, there is no other fanciness in the design section, but with these sorts of features combination, it’s definitely a provision of exquisite quality and robust engineering.

Performance and Temperature Ranges:

The temperature range is definitely not extraordinary when we see gigantic Milwaukee 2267-20 and Amprobe IR-730. Yet, many other performance elements are sweetened in this advanced infrared oven thermometer; it easily surpasses the most rivaling Ooni 1100F with a 1202F reach.

Moreover, if you need a versatile gadget for multiple areas of assistance, the adjustable 0.10 to 1.0 emissivity superbly gets the job done. Fluke claims it’s lightning fast and can give 40% quicker results than its basic version, which measures in 300ms vs. 500Ms. Brain put this claim in real testing, giving us a result in 380ish milliseconds, which is a nice jump in improvement.

Furthermore, for absolute and concrete accuracy seekers, the NIST certification and 12:1 D:S ratio make it the most accurate infrared thermometer in the market with +/- 1.0c accuracy. We tested it against our Alfa Nano because Nano’s built-in temperature gauge is the most accurate one, and the results were impressively almost similar.

This whole paradigm happens, maybe because of the dual laser pointers. But then, this also leads to a drop in battery life. The previous series was capable of 12 hours of up-time with one battery, the 62 Max version dropped to 10 hours, and this can give you 8 hours. So, if you have months-long continuous travel plans, keep a spare battery in your package.

Overall, the improvements and high-end performance are clearly a win for those who need an excellently reliable and accurate IR thermometer.


  • Superb accuracy and sharp response
  • Good practicality with easy usability and superb durability
  • Good 12:1 D:S with the quickest response
  • IP54 rating safeguards from environmental harshness
  • NIST certification makes it worthwhile for high accuracy-demanding fields
  • Tremendous temperature ranges make it more versatile


  • User manual is directionless – more pictography, less words
  • Average battery life

Alternatives to Fluke 62 Max+ – Etekcity 1025D, Milwaukee 2267-20, Klein Tools IR5

Fluke 62 Max and 62 Max+ are definitely expensive. If you want to discover almost similar credentials but much lesser pricing, Etekcity 1025D automatically comes into the competition. With under 40$, you get adjustable emissivity, 12:1 D:S ratio, 1000F+ highest range, and good battery life. The only lag that may affect accuracy-conscious minds is the lack of certifications which Fluke 62 Max+ takes pride in. However, if you are marginally short of budget and need to pick a good value-to-money IR thermometer, Etekcity is a way to go indeed.

3. FLIR TG54 – Most Accurate Infrared Thermometer



Why Do We Choose This: Although expensive, it depicts great craftsmanship and quality supremacy on first impressions. Definitely, it’s not for budgeted users, but for people who are much more conscious about the right choice while spending a good budget, FLIR TG54 is a good option beyond Fluke. The sharpest accuracy, robust build quality, extensive temperature range, and optical power make it a strong contender for Heavy industries to domestic usage. And apart from all these, we like the performance stability.

Who’s it For: Upper-moderate budget users, Restaurant owners, industry workers

Who Should Avoid It: Budget Users, Chefs who can compromise on accuracy

The Best Selling Points of FLIR TG54:

  • Sharpest Accuracy: We also tested Fluke 62 Max+, but it’s more stable and sharpest than its rival.
  • Extensive Optical Range: With the 24:1 range, it is ahead of many standard 20:1 thermometers.
  • Superb Build Quality: Spending 100+ bucks and getting a somewhat off-standards product? You deserve much more than this. With its supreme build quality and shiny looks, it definitely looks premium in the hands and tools bag.

Design and Build Quality:

From a design perspective, it’s similar to other heat sensor guns. However, for black lovers, the glossy black finish will just be a fascinating thing at the very first impression. The grip design is also very ergonomic, but it’s not the lightest in the market, so patients with arthritis may have a problem holding this.

The plastic body feels sturdy, and the smooth plastic texture doesn’t feel cheap on your hands. The manufacturer also claims 3m as a safe height for accidental or intentional drops. Our own guy, Leonard, tested this with 2m and found this thing super stable after this shock.

While this may be good news against wear and tear scenarios, we found a miss here. As a 100 bucks gadget, we haven’t got any information about quality certifications. Also, it doesn’t have any IP rating, which is a slight bummer when we compare it with Fluke 62 Max+, an IP54-rated infrared meter.

This may not be a matter of concern for regular users, but this can give second thoughts to industry workers.

Anyways, when talking about safety, the Class1 0.39mW laser output is there. While we haven’t performed any Hazard testing on any living object, we left it to the claims of the manufacturer.

Note: For those who don’t know about class1 lasers, this item is a product that emits a laser of Class I, which is low-powered and not harmful to the eyes. This information is important to consider for safety purposes and to ensure that the device is being used correctly and responsibly.


Performance and Temperatures:

It was crystal clear that the FLIR TG54 was a heavyweight performer. I mean, just take a gander at that accuracy versus optical range! The Fluke 62 Max+ may have the reputation of a “Class A” performer in the market with +/-1.0 accuracy, but this bad boy flaunts +/-0.5 accuracy, putting it in the ring with the big boys.

But let’s not judge a book by its cover – is this infrared thermometer a practical powerhouse as well?

We tested this Hulk of thermometers for pizza ovens on Alfa Nano, and the reading barely changed. This also brings a massive 24:1 optical range which we tested at different distances. Impressively, it didn’t fluctuate that much when we moved farther from the hot spot.

In addition to its impressive range, the adjustable emissivity feature gives this gadget some serious street cred. We tested the electrical wiring of our electric pizza ovens, bbq grills, and convection ovens; the emissivity shift was flawless.

The only complaint we had was the slow boot. While comparing it with Fluke’s 1-sec boot, this has a comparatively sluggish startup, taking a leisurely 4-5 seconds.

But is this a matter of concern?

This may be a thumbs down in high-tech industries or sensitive working areas. However, this won’t make a huge difference for regular domestic and commercial pizza-making activities. Yet, stability and the right temperatures make a world of difference.


  • Absolute robust build quality and attractive aesthetics
  • Great combination of features
  • The colorful screen is easily readable in the sun and low lights.
  • Gives alarm for high low temperatures
  • Most crispy-crunchy accuracy we have tested so far
  • Good usability with adjustable emissivity
  • Class1 laser to make it safe for humans and animals


  • Doesn’t have IP ratings for weather resistance
  • Doesn’t provide any information about Certifications.

Alternative to FLIR TG54Klein Tools IR10:

Well, there are many other expensive tools that can compete with FLIR TG54. But if you want to enjoy similar build quality and performance stability at less pricing, there is Klein Tools IR10. The spot-to-distance ratio is somewhat lower than FLIR, but they both perform relatively neck-neck, considering accuracy and temperature range. And for build quality, IR10 isn’t that glossier but equally good against drops and other mishaps. The only thing that raises IR10 in the competition is much lower pricing than FLIR TG54. 

4. EtekCity 1025D – Best Budget Temperature Gun


EtekCity 1025D

Why Do We Choose This: Well, Etekcity has many legendary temperature measurement devices, but we choose Etekcity 1025D rather than the 1080 and 1022D models due to better value for money. Though there isn’t much flashy representation of features and specs, this model is all about great practicality and a sensible combination of specs to leverage experts in their particular niches. This is one point! But with all these combinations, we really loved the most competitive pricing, which gets the talk of the town.

Who’s is It For: Cooking experts, turtle tanks, mechanics, and industry experts

Who Should Avoid It: Not a medical grade thermometer, premium gadget lovers

The Best Selling Points of EtekCity 1022:

  • Most Sensible Arrangement of Features: It’s not about hitting the aggression while planning specs. The most sensible and practical combination of features brings it worldwide recognition.
  • Competitive Pricing: We are probably repeating it again, but competitive pricing under 30$ really fascinated and forced us to experiment with this tool.
  • Dual Laser For More Accuracy: While the expensive Ooni and Gozney come with only a single laser module, Etekcity gets dual laser for more accuracy

Design and Build Quality:

Improving from its sibling 1022D, this model got a lengthier handle to cater to people with slightly bigger hands. Most pizza oven thermometers render a length of 5-6 inches, which remains rightful for small-medium hand sizes. Etekcity 1025D, getting bigger from its previous version, holds 8.86” in length that becomes much bigger in size.

So, people with slightly bigger hands may find it perfectly fitted in their hands and chunkier to feel with 11+ ounces of weight.

Again, the overall gun-like structure remains the same, but here we get a glossy finish anti-scratch polish/coating to keep your gadget in pristine condition even in rough and tough conditions. And due to this glossy finish, Leonard reported a much clearer and shiny display with backlit light that doesn’t even get blind in sunlight or low light.

Though the manufacturer says it’s weather and water-resistant, we didn’t get what IP ratings this heat sensor gun got. However, we did a height-fall test, and it remained safe while testing it from a height of 1.5m. 

Overall, from a design and build quality perspective Etekcity LaserGrip 1025D showcases good aesthetics and doesn’t hold back from any premium IR thermometer.

Performance and Temperature:

The whole budget range of Etekcity covers a similar optical range of 12:1, and this isn’t the exception here. The only model 800 gets a 16:1 distance-to-spot ratio but furnishes a fixed 0.95 emissivity. That’s why we choose the 1025D with a very practical 12:1 ratio and adaptable emissivity, and our preference rightly goes with this model for achieving better value for money.

Well, anyways, Brian took this gadget and reported a 1022F temperature range which is enough for Neapolitan and artisan pizza lovers who mostly prefer wood-fired or stove ovens. Though accuracy-wise, it isn’t that fancy. It rigs +/- 2c as per the company’s claim.

Yet, it fluctuates from 6-9F, which isn’t a big deal if you aren’t purposed to map down critical temperature ranges.

Coming to the response time, it also aligns with the industry standard of </=500ms. Nonetheless, we didn’t find it sluggish, and it can fulfill anyone’s purpose with great ease.

The only complaint we had with the model, like other IR thermometers, is that it needs to be more accurate when we measure in dusty, steamy, and smoggy situations. Etekcity 1025D fluctuates a bit but doesn’t make a big difference.

Overall, this sort of performance and feature set under a budget makes it an ideal choice for budget and performance-hungry users.


  • Good practicality and sensible feature set
  • Adaptable emissivity in most competitive pricing in the market
  • The dual laser provides great precision and accuracy
  • Attractive glossy design with a bigger length for big hands
  • Excellent build quality raises its class


  • Temperature fluctuates a bit in particular scenarios

Alternatives to Etekcity 1025D:

While Etekcity 1025D is famous for its accuracy led practicality, we only found NEIKO 52911A to be the perfect alternative. Specification-wise, these both are identical IR thermometers. Nonetheless, we found Etekcity to be more accurate than NEIKO. But that doesn’t mean NEIKO compromise entirely on Accuracy, it’s just short ranged and fluctuates when you go farther. If you are extremely tight on budget, NEIKO is slightly inexpensive than EtekCity 1025D.

5. Klein Tools IR5 – Value-to-Money Midrange IR Thermometer


Klein Tools IR5

Why Do We Choose This: To be honest, we considered Fluke 62 Max+, which is an all-rounder, posing great stability, durability, and performance. Yet, it definitely showcases some price luxury. But then, if you need a best-infrared thermometer with a similar portfolio but at less pricing, Klein Tools IR5 is undoubtedly a good choice. With a decent temperature range, good optical power, dual laser, and better battery life, it covers many performance departments very well at competitive pricing. 

Who’s it For: Mid-range budget users, travelers, wood-fired pizza oven chefs. 

Who should Avoid it: Highest degree (1000F+) temperature

The Best Selling Points of Klein Tools IR5:

  • Good Durability and Build Quality: The plastic body doesn’t feel cheap, and it holds a claim of safety against 2.2M fall.
  • Excellent Optical Power: With a 12:1 range, you certainly have accurate temperature measurements from a safe distance
  • Optimal Combination of Features in Competitive Pricing: Since it’s a midrange IR thermometer, it nourishes good value for money with a great combination of usability and performance features.

Design and Build Quality:

For the design part, it’s also a gun mold design like other infrared oven thermometers in the market, nothing fancy with no unique bells and whistles. Yet, the gripping design and length of the hand-held vertical body are pleasingly optimized for small-medium hands. The 9.9 ounces isn’t the lightest in the market but also doesn’t feel cumbersome to weak wrists.

But yes, it may be problematic for arthritic or other orthopedic patients, but we can’t tell this by any surety. 

As we made Fluke 62 Max and Max+ as a point of comparison, IR5 slightly falls in robustness but still contrives to grab good ability against rough and tough scenarios. Though it does not deliver any water and dust-resistant ratings, it managed to remain intact and workable in a 1.5-meter fall in our testing.

The manufacturer claims it can pose great endurance against a 2.2m fall, but Leonard tested it for 1.5m, and we can only say it competently meets the standards.

On the usability part, the manufacturer has well-kept all audiences in mind while giving a combination of C/F modes, auto shutdown for optimal battery performance, and other essential temperature settings. Our only complaint was the unavailability of beeping alerts. It may not be an issue for many chefs, but beeping confirms the temperature status, which is missing here.

Klein Tools IR5

Performance and Temperature Range:

We call it an all-rounder for many reasons. Yes, there are some goods and average parts here, but keeping an “all-rounder” term in mind, it checks all green boxes to be a top-rated infrared thermometer in the market.

First of all, the optical range is good. The 12:1 ratio allows measuring a safe-distance temperature in volatile and harsh conditions. Moreover, the dual laser feature promotes good accuracy. Though the accuracy standards are not the highest in the market, +/-2c can give you the most accurate results in most scenarios.

It doesn’t hold the highest temperature reach with 750F as its upper node. Also, the 0.9s resting could have been improved to the very standard 0.5 sec. Yes, it’s a bit average of specs here. However, we really liked the adaptable emissivity feature, which remains a lack in many of this league’s best kitchen infrared thermometers.

Technically, IR5 covers most of its lagging here as adaptable emissivity makes it a versatile heat sensor gun in its league. However, if this doesn’t meet your requirements, an upper version of this model (IR10) can do the purpose excellently with 1202 temperature and much more extensive 20:1 optical power.


  • Good combination of performance and features
  • The backlit display makes it highly usable in low lights
  • Multiple temperature modes for versatility
  • Adaptable emissivity to measure different substance’s temperature
  • Good Battery life, about 12hrs.


  • It doesn’t beep

Alternatives to Klein IR5Ooni Plastic Thermometer, Nubee NUB8550H

Considering the pricing and features, the Ooni IR thermometer is our closest alternative to Klein Tools IR5. Coming with a midrange intent, it presents neck-neck competition to Klein Tools IR5 in almost every performance department. Though the 750c high-temperature range is almost similar to Klein tools, Ooni hasn’t mentioned its accuracy and optical power. However, we measured it from 10 inches, giving similar results to Klein tools IR5. But then, it lacks marginally in response rate.

People Also Ask – FAQs:
