The best infrared thermometer depends on your specific heat range. For extreme industrial or forge needs exceeding 2,000°F, the Raytek RAYR3IPLUS1ML is the performance benchmark. For baking, pizza ovens, and workshop stone, the VEVOR Infrared Thermometer series provides a reliable, high-max-temp solution, while the ThermoWorks Industrial IR Gun acts as the preferred choice for those prioritizing proven durability and professional-grade accuracy in regular high-heat tasks.
If you're measuring stone for a pizza oven, hearth, kiln, or masonry application, I'd prioritize high maximum temperature, adjustable emissivity, and a tight distance-to-spot ratio.
My picks
ThermoWorks IRK-2 - $99.00 (ThermoWorks)
VEVOR -40°F to 2732°F Infrared Thermometer - $39.90 (VEVOR)
FLIR TG56-2 - $226.99 (Apollo Industries)
Fluke 572-2 - $945.00 (Network Devices Inc.)
Best for most stone/pizza-oven use:
— $99, designed specifically for high-heat surfaces including pizza stones, with a circular laser targeting system. This is the one I'd look at first if you're measuring cooking/hearth stone rather than industrial metal.
When measuring the temperature of stone—whether it's a high-heat pizza stone (7 5 0∘F−9 5 0∘F ) or extreme industrial/kiln stone and masonry (1000∘F 1000 raised to the composed with power F 1 0 0 0∘F to over 2000∘F 2000 raised to the composed with power F 2 0 0 0∘F )—standard household infrared guns that max out at 1,0 2 2∘F might fall short or operate too close to their limit.[1]
Best inexpensive high-temperature option:
— rated up to 2732°F / 1500°C, adjustable emissivity from 0.10–1.00, dual laser. At around $40, it gives you a huge temperature ceiling for the money.
Higher-end professional option:
— up to about 2372°F, with 30:1 distance-to-spot and Type-K thermocouple capability.
Premium industrial instrument:
— IR range to 1652°F, but exceptionally good 60:1 optics, adjustable emissivity, dual lasers, and excellent build quality. Fluke specifies ±2°F or ±1% above 32°F.
One important thing about measuring stone
The maximum temperature isn't the only specification that matters. Stone is a relatively emissive surface, but different stone finishes can give IR guns different readings. You want adjustable emissivity and should keep the gun reasonably close to the surface.
For example, the Fluke 572-2 lets you set emissivity from 0.10 to 1.00 and has a 60:1 distance/spot ratio.
If you're talking about pizza-oven stone, tell me roughly what temperature you're expecting — 500°F, 800°F, 1000°F, 1200°F+ — and whether you want to spend $50, $100, $200, or $500+. I can narrow it down considerably.
When measuring stone temperature (whether it’s a high-heat pizza stone in a 900∘F 900 raised to the composed with power F 9 0 0∘F wood-fired oven or stone masonry in industrial/industrial-art settings), standard kitchen IR guns (which usually cap out at 1,0 0 0∘F or less) might fall short.
The best high-temperature infrared thermometer guns combine an extreme maximum range, adjustable emissivity (crucial for accurate stone readings), and a sharp distance-to-spot ratio.
Top High-Max-Temp Infrared Thermometer Guns
VEVOR Infrared Thermometer (-40°F to 2732°F) /
Max Temp: 2,7 3 2∘F (1,5 0 0∘C)
Distance-to-Spot Ratio: 50:1
Why it's great: If you need an absolute powerhouse with a massive ceiling, this industrial-grade dual-laser unit handles extreme heat environments. The 50:1 ratio means you can stand quite far back from a raging hot pizza oven or stone structure and still target a precise small spot. It also features fully adjustable emissivity (0.1 0−1.0 0).[1]
VEVOR Dual-Mode IR Thermometer with K-Type Thermocouple (-22°F to 2192°F)
Max Temp: 2,1 9 2∘F (1,2 0 0∘C)
Why it's great: This dual-mode gun gives you both non-contact IR surface measurement and a plug-in K-type thermocouple probe. It’s fantastic for stone because while IR gives you a fast surface read, emissivity on reflective or uneven stone can sometimes skew data; having a backup contact probe lets you cross-reference accuracy.[1]
ThermoWorks Industrial IR Gun
Max Temp: Generally up to around 900∘F 900 raised to the composed with power F 9 0 0∘F to 1,0 0 0∘F (depending on the specific industrial model variant)
Why it's great: If your stone temp doesn't exceed 1,0 0 0∘F (common for high-end baking and outdoor pizza ovens), ThermoWorks is the gold standard for culinary and pro-surveillance accuracy, featuring ultra-fast response times and adjustable emissivity.
Pro-Tip for Measuring Stone
Stone has an emissivity value typically around 0.85 0.85 0.8 5 to 0.95 0.95 0.9 5 . Ensure whichever gun you buy has adjustable emissivity so you can dial it in; otherwise, glossy or dense stones might return falsely low temperature readings.
Are you measuring the stone for pizza/cooking (maxing out around 800∘F 800 raised to the composed with power F 8 0 0∘F–1000∘F 1000 raised to the composed with power F 1 0 0 0∘F ) or for industrial/kiln/masonry work (requiring 1,5 0 0∘F+positive+)? Let me know your precise temperature target so I can narrow down the best fit.
If this is a pizza oven stone: get the ThermoWorks Industrial IR Gun or a similar 1,000–1,500°F model. A 3,000°F unit is unnecessary unless you have a special application.
If you mean fireplace stone, kiln brick, forge, or unknown high heat: I would step up to the Extech 42570 or a high-temp VEVOR model.
A couple of questions would let me narrow it to one:
What kind of stone — pizza oven, granite, fireplace, kiln/refractory, or something else?
What temperature do you expect (for example 900°F, 1500°F, 2500°F)?
When measuring stone temperatures (such as for masonry, pizza ovens, kilns, or hearths), you need a high maximum temperature range, a good distance-to-spot ratio, and adjustable emissivity (stone usually has an emissivity around 0.85 0.85 0.8 5 to 0.95 0.95 0.9 5 , but it varies depending on whether it's polished, rough, granite, sandstone, etc.).
The top-tier infrared thermometer guns featuring exceptionally high max temperatures vary depending on your budget and accuracy requirements:
Max Temperature: 2732∘F 2732 raised to the composed with power F 2 7 3 2∘F (1500∘C 1500 raised to the composed with power C 1 5 0 0∘C)
Distance-to-Spot Ratio: 50:1
Why it’s great for stone: This is a professional-grade instrument tailored for high-heat ceramics, glass, and metal/stone applications . It features a clear 4-point laser to outline your exact measurement area so you don't misread a hot spot, plus an integrated emissivity table to help dial in the precise reading for specific materials. It also includes a port for an external K-type thermocouple probe.
Max Temperature: 1652∘F 1652 raised to the composed with power F 1 6 5 2∘F (900∘C 900 raised to the composed with power C 9 0 0∘C)
Distance-to-Spot Ratio: 60:1
Why it’s great for stone:Fluke is the gold standard for industrial durability and precision. A 60:1 ratio means you can stand quite far back and still get a tiny, pinpoint accurate spot reading on a searing-hot stone surface. It includes dual lasers for precise targeting, onboard data logging, and a K-type thermocouple input. (Note: If your stone work exceeds 1652∘F 1652 raised to the composed with power F 1 6 5 2∘F , look to the Testo above, but for most hearth and oven applications, this is as reliable as it gets).
Max Temperature: 2732∘F 2732 raised to the composed with power F 2 7 3 2∘F (1500∘C 1500 raised to the composed with power C 1 5 0 0∘C)
Distance-to-Spot Ratio: 50:1
Why it’s great for stone: If you need extreme high-temp capability on a budget, this VEVOR unit offers adjustable emissivity (0.1 0--1.0 0 ), dual lasers, and a massive temperature ceiling for a fraction of the cost of lab-grade gear.[1][2][3]
To help narrow down the ideal choice, could you tell me:
What maximum temperature do you expect the stone to reach?
What is the application (e.g., a wood-fired pizza oven, industrial kiln, or geological/fire testing)?
Yes. If you mean stone in a pizza oven, fireplace, kiln, or similar high-heat application, I’d prioritize adjustable emissivity + a high temperature ceiling + a good distance-to-spot ratio, not simply the biggest advertised temperature.

To help narrow down the ideal pick, tell me:
What kind of stone or application are you measuring (e.g., pizza oven, fireplace, industrial kiln)?
What temperature range do you actually expect to hit?
When measuring the temperature of hot stone (whether it's a pizza/baking stone around 5 0 0∘F−9 0 0∘F , a masonry fireplace, or industrial firebrick/kiln surfaces exceeding 1500∘F 1500 raised to the composed with power F 1 5 0 0∘F ), you need a thermometer with:
Adjustable Emissivity: Stone typically has an emissivity around 0.85 0.85 0.8 5 to 0.95 0.95 0.9 5 , but adjustable settings ensure accuracy if the stone is polished, dusty, or mixed with other materials.
A High Distance-to-Spot (D:S) Ratio: Higher ratios let you stand safely back while measuring a precise spot rather than averaging a giant area.

To help narrow down the exact model you need, let me know:
What kind of stone application are you working with (pizza oven, fireplace, kiln, etc.)?
What maximum temperature do you expect the stone to reach?
Yes. If you’re measuring hot stone, I’d avoid choosing purely by the highest advertised temperature. Adjustable emissivity and distance-to-spot ratio are especially important for getting a useful reading from stone.
My picks
Extech 42570 - $861.03 (Exact Tool & Supply)
VEVOR 2912°F Dual-Mode - $45.90 (Best Buy)
VEVOR 2732°F Dual Laser - $39.90 (Best Buy)

Best high-end:Extech 42570 — measures up to 3,992°F (2,200°C) and has 50:1 optics and adjustable emissivity. This is overkill for a pizza oven, but excellent if the stone could get extremely hot.
Best value/high-temperature:VEVOR 2912°F (1,600°C) dual-mode — roughly $46 currently, with 50:1 distance-to-spot, adjustable emissivity, dual laser, and a K-type thermocouple input.
Best professional choice for ~1,600°F and below:Fluke 572-2 — tops out at 1,652°F (900°C), but has excellent 60:1 optics, adjustable emissivity, and very good published accuracy.
Budget option: VEVOR's 2,732°F model is inexpensive and gives plenty of temperature headroom.
If this is for a pizza oven stone, I would personally buy the VEVOR 2912°F 50:1 model unless you want professional-grade reliability. You don't actually need a 3,000°F+ instrument for a typical pizza stone, but the extra headroom is useful.
One important caveat: IR guns measure surface radiation, not the actual internal temperature of the stone, and emissivity can significantly affect the reading.
If you tell me what kind of stone and its expected maximum temperature (pizza oven, kiln, fireplace, granite, refractory brick, etc.), I can give you one specific model to buy, including the best price I find.
If you’re measuring stone temperature—especially pizza/baking stones, fireplace stone, kiln stone, or masonry—I’d prioritize high maximum temperature + adjustable emissivity + a good distance-to-spot ratio.
My top picks
ThermoWorks IR-PRO-75 - $439.20 (ThermoWorks)
Best overall for very hot stone: ThermoWorks IR-PRO-75
Measures up to 1,600°C / 2,912°F
Excellent 75:1 distance-to-spot ratio
Adjustable emissivity

What I'd buy
If this is for pizza/baking stone temperatures, I'd get the ThermoWorks IR-PRO-75. You probably don't actually need 2,900°F, but the combination of high range, 75:1 optics, and adjustable emissivity makes it substantially more useful than the typical $30–50 IR gun.
If your stone will never exceed ~1,200°F, the Fluke 62 MAX+ is another excellent choice: it goes to 1,202°F, has adjustable emissivity, dual lasers, and a 12:1 ratio.
One important point: stone can have a different emissivity than the factory default on an IR gun. For the most accurate reading, use a thermometer with adjustable emissivity and make sure you're measuring a sufficiently large area relative to the gun's distance-to-spot ratio.
If you tell me what kind of stone you're measuring (pizza stone, natural stone countertop, fireplace, kiln, etc.) and roughly the temperature you expect, I can narrow this down to the best 2–3 choices and price points.
To safely and accurately measure high-temperature stone, look for a thermometer with an extended max range , an adjustable emissivity setting (crucial for accurate stone readings, typically set around 0.9 3−0.9 5 for masonry/brick/stone), and a solid Distance-to-Spot (D:S) ratio so you don't have to stand dangerously close to extreme heat sources.[1]
