I need to measure stone temp. What is the best infrared thermometer gun with a high max temperature?

When measuring the temperature of stone (like a pizza stone, hearth, kiln shelf, or geological sample), you need a high max temperature and an adjustable emissivity setting because stone typically has an emissivity around 0.93 0.93 0.9 3 to 0.96 0.96 0.9 6 , but variations in texture, finish, and composition can skew readings if the gun is locked at a default 0.95 0.95 0.9 5.

Depending on how hot your stone gets (e.g., standard pizza stone vs. high-heat industrial kiln/forge stone), here are the best high-temperature infrared thermometer guns available:

• Max Temperature: 3272∘F 3272 raised to the composed with power F 3 2 7 2∘F (1800∘C 1800 raised to the composed with power C 1 8 0 0∘C)
• Distance-to-Spot Ratio: 1 0 0∶1
• Why it’s great: ThermoWorks is the gold standard for thermal accuracy.

To help narrow down the best fit, what maximum temperature do you expect the stone to reach , and what type of setting or oven is it in?

For measuring stone temperature, the best infrared thermometer depends on how hot the stone gets (pizza oven stone vs. fireplace/kiln/refractory stone). For most hot-stone applications, I would prioritize:

• High maximum temperature
• Adjustable emissivity (very important because stone surfaces vary)
• Good distance-to-spot ratio (so you measure the stone, not the surrounding air)
• Reliable calibration/accuracy

My top picks:

Triplett IRT500 High-Temp IR Thermometer

$175.99

Extech 42512 Dual Laser IR Thermometer

$209.99

Extech 42570 High Temperature IR Thermometer

$861.03

Best overall for hot stone: Triplett IRT500 High-Temp IR Thermometer

• Measures surface temperature without contact and includes a Type K thermocouple option.
• Good fit for stone because you can verify readings with a contact probe when needed.
• Better choice than many ultra-high-range budget guns because stone emissivity can make cheap IR readings misleading.

Best professional/high-temperature choice: Extech 42570 High Temperature IR Thermometer

• Very high range: up to about 3992°F (2200°C).
• Intended for industrial hot surfaces.
• Overkill for pizza stones, but useful for kilns, furnaces, or very hot refractory materials.

Best value if you need around pizza-oven temperatures:

• Claims a very high range (up to 2732°F) and adjustable emissivity.
• Good on paper for stone ovens, though I would trust a calibrated professional unit more for critical measurements.

If your stone is a pizza oven stone:

You probably do not need a 3000°F gun. A good 1000–1500°F instrument is usually enough. The Triplett IRT500 High-Temp IR Thermometer or a quality ThermoWorks/Fluke unit is likely a better investment because accuracy matters more than extreme range.

A note on stone: infrared guns measure surface temperature, and polished/light-colored stone can give inaccurate readings unless emissivity is set correctly. Adjustable emissivity is one of the most important features.

If you tell me what kind of stone (pizza oven, wood stove, fireplace, kiln, BBQ pizza stone, etc.) and the expected temperature range, I can narrow it to the best model.

For measuring stone temperature, the “best” infrared thermometer depends on whether you mean a pizza oven/hearth stone or extremely hot refractory stone (kiln/forge/furnace). The biggest mistake is buying a gun with a huge advertised temperature range but poor accuracy, optics, or emissivity control.

If this is for a pizza oven or cooking stone

You usually do not need 2000°F+. A quality gun around 1000–1200°F is generally enough. I would favor accuracy, adjustable emissivity, and a good spot ratio over a huge maximum rating. Models like the ThermoWorks Industrial IR line are popular for this type of use because of those features.

Features I would require for stone:

• Adjustable emissivity (stone is usually high-emissivity, but polished/different surfaces can vary)
• At least 12:1 distance-to-spot ratio (higher is better)
• Dual laser or circular target so you know the measured area
• Max temperature well above your expected temperature (don’t run a 1000°F gun at its limit)

My recommendation:

• Pizza oven / hearth stone: ThermoWorks Industrial IR or similar ~1000–1200°F model
• Kiln / forge / very hot refractory stone: Fluke 572-2 if accuracy matters; VEVOR/HoldPeak-style 2700–3000°F units if budget and maximum range matter more

What kind of stone are you measuring, and what temperature do you expect (e.g., pizza oven 900°F, kiln 2000°F, forge 2500°F)? I can narrow it to one model.

When measuring the temperature of stone (whether it's a pizza/baking stone, a fireplace hearth, or industrial masonry), you need an infrared (IR) thermometer that handles high heat while offering adjustable emissivity . Stone usually 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 unevenly heated.

The best infrared thermometer guns with high maximum temperature ranges vary by your specific application and budget:

1. The Professional Choice:

If you can tell me how hot the stone is expected to get and what you are using it for (e.g., residential pizza oven vs. industrial stone kiln), I can narrow down the ideal distance-to-spot ratio and budget for your setup.

If you're measuring stone, refractory brick, kiln shelves, forge linings, or pizza oven floors, I'd prioritize these features over just the maximum temperature:

• Adjustable emissivity (stone is typically around 0.95)
• High distance-to-spot (D:S) ratio (30:1 or higher is ideal)
• A temperature range comfortably above your expected maximum
• A reputable brand, since accuracy often matters more than an extra few hundred degrees of range.

Here are the models I'd recommend:

Highest temperature handheld options

If you truly need temperatures above 3000°F:

• BTMETER BT-1800 (3272°F / 1800°C)
• Similar industrial pyrometers rated to 3272°F

These are intended for furnaces, foundries, and kilns rather than everyday cooking.

My recommendations by application

• Pizza stone (700–1000°F): ThermoWorks Hi-Temp Industrial
• Kiln shelves or refractory brick (1500–2300°F): Fluke 572-2 or the VEVOR 2912°F model
• Forge or furnace stone (>2500°F): A 3000°F+ pyrometer such as the BTMETER BT-1800

One other tip: stone usually has an emissivity around 0.90–0.95. A thermometer with adjustable emissivity will generally give much more reliable readings than one with a fixed setting, even if both advertise the same maximum temperature.

What kind of stone are you measuring?

• Pizza oven stone
• Soapstone
• Granite
• Kiln shelf
• Forge/furnace refractory

That will determine whether you really need a 3000°F-class instrument or if a 1600–1800°F model is the better choice.

3 Important Tips for Measuring Stone

• Adjustable Emissivity: Because stones (like granite, marble, or pizza stones) are not perfectly reflective like metal, their emissivity differs. High-end tools like the ThermoWorks IR-PRO feature adjustable emissivity so you can dial in the exact material type for a more accurate reading Professional Hi-Temp IR w/Dual Laser (IR-PRO).
• Distance to Spot Ratio (D:S): A 50:1 ratio means you can safely measure a 1-inch area of a very hot stone from 50 inches away.
• Reflective Stones: If your stone is highly polished or wet, infrared readings can be less reliable because they detect surface reflections rather than true temperature Best Infrared Thermometer in 2026? - The Garage Journal.
