For measuring stone temperature, the “best” infrared thermometer depends on whether you mean a pizza stone/fireplace stone (typically under ~1,000°F) or extremely hot refractory/kiln stone. The highest max temperature is not always the most accurate choice—adjustable emissivity and a good distance-to-spot ratio matter a lot with stone.
My top picks:
ThermoWorks IR-PRO
ThermoWorksThis is the one I would buy for a wood-fired pizza oven, masonry oven, refractory stone, or serious cooking setup.
VEVOR High Temperature IR Thermometer
Good if you truly need extreme headroom (kiln, forge, furnace, ceramics), though the extra range does not automatically mean better accuracy on stone.
Fluke 64 MAX / similar Fluke industrial models
Cheap IR guns that only go to 700–900°F may work, but if your stone is near pizza-oven temperatures they leave little safety margin. Also avoid fixed-emissivity models; stone surfaces can give misleading readings if emissivity is wrong.
A quick recommendation:
What kind of stone are you measuring (pizza oven, granite, fireplace, kiln/refractory), and what temperature range do you expect? I can narrow it to the best model.
When measuring the temperature of stone (whether it's a pizza stone, fireplace hearth, stone forge, or masonry), standard cooking or HVAC infrared thermometers (which usually max out around 500∘F 500 raised to the composed with power F 5 0 0∘F to 1000∘F 1000 raised to the composed with power F 1 0 0 0∘F ) won’t cut…

For measuring stone temperature, the “best” infrared thermometer depends on how hot the stone gets. If you mean pizza stone, kiln brick, fireplace stone, forge, or industrial refractory, the choice changes a lot.
One important detail: stone is a low-reflectivity surface, but different stones have different emissivity. A thermometer with adjustable emissivity will generally give more trustworthy readings than one with a huge temperature range but fixed settings.
If you tell me what stone (pizza stone, granite countertop, fireplace, kiln brick, etc.) and expected temperature, I can narrow it to one model.
When measuring high stone temperatures (such as a pizza stone, kiln bricks, or industrial hearths that can easily exceed 500∘F 500 raised to the composed with power F 5 0 0∘F to 1000∘F 1000 raised to the composed with power F 1 0 0 0∘F +), you need a reliable gun with **adjustable emissivity** (stone emissivity…

For measuring stone temperature, the “best” infrared gun depends on whether you mean a pizza stone, fireplace/refractory stone, kiln, or something industrial. The biggest mistake is buying only by the advertised max temperature — emissivity adjustment and distance-to-spot ratio matter a lot with stone.
Here are the top choices:
Extech 42570 High Temperature IR Thermometer
VEVOR Dual-Mode High Temperature Infrared Thermometer
Fluke 62 MAX+ Infrared Thermometer
Triplett IRT500 High-Temp IR Thermometer or a similar cooking-focused high-temp IR gun
A few specs I would not compromise on:
What kind of stone are you measuring — pizza oven stone, fireplace/masonry, kiln, or something else? That changes the best choice quite a bit.

Top Infrared Thermometer Guns for High-Heat Stone
Tips for Measuring Stone Temperature Accurately
If you can tell me what kind of stone you are measuring (e.g., an outdoor pizza oven baking stone vs. industrial masonry) and the maximum expected temperature , I can narrow down the ideal distance-to-spot ratio you'll need.
If you’re measuring **very hot stone**—pizza-oven stone, refractory stone, kiln shelves, forge lining, etc.—I’d prioritize **high maximum temperature + adjustable emissivity + a good distance-to-spot ratio**. ### My picks ### [VEVOR High-Temperature IR…
If you’re measuring very hot stone—pizza-oven stone, refractory stone, kiln shelves, forge lining, etc.—I’d prioritize high maximum temperature + adjustable emissivity + a good distance-to-spot ratio.
$39.90
Best value for very high temperatures: VEVOR’s high-temp model reaches 2912°F / 1600°C, has adjustable emissivity, and dual lasers. It’s inexpensive enough that it makes sense if you need a lot of temperature headroom.
Best professional choice: Testo 835-T2 — this is the one I'd buy if accurate measurements are important. It reaches 2732°F / 1500°C, uses 50:1 optics, has 4-point laser targeting, and is specifically designed for high-temperature industrial applications.
Best rugged industrial option: Fluke 572-2 — max 1652°F / 900°C, but excellent optics with a 60:1 distance-to-spot ratio and dual lasers. If your stone stays below ~1600°F, this is a very serious instrument.
Don't automatically buy the Fluke 62 MAX+: it's an excellent thermometer, but its maximum is only 1202°F / 650°C, so it isn't the right choice if you're specifically looking for a high-temperature ceiling.
| Your stone temperature | I'd get |
|---|---|
| Up to ~1,000°F | ThermoWorks Industrial IR |
| 1,000–1,600°F | Testo 835-T2 |
| Up to ~2,900°F and budget-conscious | VEVOR 2912°F |
| Up to ~1,650°F, rugged/pro-grade | Fluke 572-2 |
ThermoWorks' Industrial IR is particularly nice for stone because it has adjustable emissivity, although its range is considerably lower than the Testo/VEVOR options.
One important point: if you're measuring stone, don't chase the highest advertised temperature alone. Emissivity adjustment and optics matter enormously. A cheap gun claiming 3,000°F isn't necessarily accurate at 1,500°F.
If you tell me what kind of stone you're measuring and the approximate temperature you're expecting (e.g. pizza oven at 900°F, kiln at 2,000°F, fireplace stone, etc.), I can narrow it down to one specific model.
If you’re measuring **hot stone**, especially pizza-oven/refractory stone, I’d prioritize **temperature range + emissivity adjustment + a tight distance-to-spot ratio**. ### My top pick: Extech 42570 ### [Extech 42570 Infrared…
If you’re measuring hot stone, especially pizza-oven/refractory stone, I’d prioritize temperature range + emissivity adjustment + a tight distance-to-spot ratio.
$861.03
The Extech 42570 is the one I’d choose if you specifically want a high maximum temperature. It measures -50°C to 2,200°C (-58°F to 3,992°F), has 50:1 distance-to-spot, dual lasers, adjustable emissivity from 0.10–1.00, and a 100 ms response time.
One important caveat: above 1,000°C / 1,832°F, Extech specifies the accuracy as typical rather than a full guaranteed accuracy specification, and the stated accuracy is around ±5% + 2°C in that range.
$574.99
The Fluke 568 is an excellent industrial thermometer, but its IR range tops out at 800°C / 1,472°F, so I wouldn't pick it if maximum temperature is your primary concern.
The Fluke 572-2 goes to 900°C / 1,652°F and has an excellent 60:1 optical ratio, but it's considerably more expensive and still doesn't approach the Extech's 2,200°C maximum.
There are inexpensive guns claiming 1,500–1,800°C+, such as the BTMETER units:
$139.49
$162.49
$199.95
The CEM DT-8867H, for example, is specified to 1,650°C / 3,002°F with a 30:1 ratio and adjustable emissivity.
For stone, though, I'd spend the extra money on the Extech 42570 if you want a measurement you can trust rather than simply the highest number on the display.
One other thing: stone emissivity can make a surprisingly large difference in an IR reading. If you tell me what kind of stone you're measuring and roughly what temperature you expect (e.g. 500°F, 900°F, 1,500°F), I can recommend the best gun specifically for that application and tell you what emissivity setting to use.
When measuring the temperature of stone (whether it is a pizza/baking stone, a ceramic kiln, or a hearth/forge stone), you need a thermometer with a **high maximum temperature** range, **adjustable emissivity** (stone emissivity usually sits around 0.85 0.85 0.8 5 to 0.95 0.95 0.9 5 , but adjustable settings ensure…
When measuring the temperature of stone (whether it is a pizza/baking stone, a ceramic kiln, or a hearth/forge stone), you need a thermometer with a high maximum temperature range, adjustable emissivity (stone emissivity usually sits around 0.85 0.85 0.8 5 to 0.95 0.95 0.9 5 , but adjustable settings ensure accuracy), and a decent Distance-to-Spot (D:S) ratio so you don't have to get dangerously close to the heat.
Top-performing infrared thermometer guns with high maximum temperature capacities include:
Max Temp:−5 8∘F to 2 9 1 2∘F (−5 0∘C to 1 6 0 0∘C)
D:S Ratio: 5 0∶1
Why it's great: Features adjustable emissivity, a fast response time, max/min/average tracking, and a massive temperature range well beyond what any standard cooking or domestic stone could ever reach. It also includes a thermocouple jack for contact readings.
Max Temp:−7 6∘F to 1 0 2 2∘F or higher depending on the specific industrial line (up to 1 8 3 2∘F for specialized heavy industry units)
D:S Ratio: 1 2∶1 or 3 0∶1
Why it's great: ThermoWorks is trusted heavily for professional and culinary accuracy. If your "stone" is a pizza stone or baking hearth that maxes out around 9 0 0∘F to 1 0 0 0∘F , the circle laser pattern tells you precisely the exact physical area of the stone you are capturing.
Max Temp:−3 0∘C to 9 0 0∘C (−2 2∘F to 1 6 5 2∘F)
D:S Ratio: 6 0∶1
Why it's great: The gold standard for rugged, professional, high-accuracy industrial diagnostic work with premium optical resolution and data logging.
To help narrow down the ideal choice, what is the maximum temperature you expect the stone to reach , and what type of setting is this for (cooking/pizza oven vs. industrial kiln/forge)?
