When measuring the temperature of a stone (such as a pizza stone or a masonry/hearth surface that can reach extreme heat), you need a thermometer with adjustable emissivity (since stone has a different emissivity than shiny metal) and a high ceiling.
Top infrared thermometer guns featuring exceptionally high maximum temperatures and precise performance for stone include:
VEVOR Infrared Thermometer (-40°F to 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)
Max Temp: 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: Offers a massive industrial-grade temperature range at an affordable price. It includes dual lasers and adjustable emissivity (0.1 0−1.0 0 ), allowing you to dial it in specifically for stone surfaces from a safe distance.
Triplett High-Temp IR Thermometer with Circular Laser (IRT500)
Max Temp: 1832∘F 1832 raised to the composed with power F 1 8 3 2∘F (1000∘C 1000 raised to the composed with power C 1 0 0 0∘C)
Distance-to-Spot Ratio: 20:1
Why it's great: A brilliant professional-grade tool featuring a clear circular laser ring to define your exact target area, adjustable emissivity, and an included Type-K thermocouple probe for backup contact readings.
ThermoWorks Industrial IR with Circle Laser (IRK-2)
Max Temp: Up to 1022∘F 1022 raised to the composed with power F 1 0 2 2∘F (550∘C 550 raised to the composed with power C 5 5 0∘C ) (Check specific high-temp industrial variants if higher, though standard culinary stone needs rarely exceed 900∘F 900 raised to the composed with power F 9 0 0∘F).
Distance-to-Spot Ratio: 12:1
Why it's great: ThermoWorks is the gold standard for kitchen and high-heat accuracy. It features a full-circle laser and adjustable emissivity, making it explicitly reliable for pizza stones and heavy hearths.
Ooni Digital Infrared Thermometer
Max Temp: 1022∘F 1022 raised to the composed with power F 1 0 2 2∘F (550∘C 550 raised to the composed with power C 5 5 0∘C)
Distance-to-Spot Ratio: Optimized for close-to-mid range baking stone use.
Why it's great: If your stone is used for pizza baking, this dedicated tool comes preset for baking stones with a clear laser guide and color-coded temperature indicators.
To help narrow down the ideal choice, what maximum temperature do you expect your stone to reach, and is this for pizza/cooking or an industrial/industrial-art application?
If you want an infrared thermometer gun for measuring stone temperature with a very high maximum reading, I'd narrow it down to three things: maximum temperature, accuracy on stone, and how precisely the gun targets the area you're measuring.
My recommendation depends on how hot your stone gets. For pizza ovens and fireplaces, you don't necessarily need an industrial instrument rated for 3,000°F. For kilns, furnaces, or refractory stone, that extra range can be important.
Best high-temperature infrared thermometer guns
1. VEVOR High-Temperature IR Thermometer
(Best budget pick)
$41
Maximum: 2,912°F (1,600°C)
Very high temperature ceiling for the price.
Dual lasers and a contact K-type probe on this version.
Good budget option for hot stone, refractory material, or workshop use.
Adjustable emissivity: Look for this feature so you can configure the thermometer for your particular stone surface.
Distance-to-spot ratio: A 30:1 ratio measures an approximately 1-inch area from 30 inches away. The laser points help you aim, but they don't necessarily outline the entire measured area.
Accuracy at your actual temperature: Don't assume a gun is accurate just because its maximum rating is high. Check its specified accuracy at the temperature you intend to measure.
One question so I can recommend the right one
What kind of stone are you measuring, and roughly how hot will it get?
If you mean very hot stone/brick/ceramic surfaces—especially pizza-oven floors, kiln shelves, masonry, or refractory stone—the key is not simply “highest rated.” You want a temperature ceiling above your actual surface temperature, adjustable emissivity, and a reasonably tight distance-to-spot ratio.
🥇 Best overall for stone: ThermoWorks Industrial IR Gun
ThermoWorks's Industrial IR Gun is particularly well matched to stone because it has adjustable emissivity from 0.1–1.0, a 12:1 distance-to-spot ratio, and a –76°F to 1,022°F measurement range. ThermoWorks specifies ±2.7°F accuracy from 55–95°F and ±4°F or 2% of reading from 32–1,022°F.
That's a very good balance for a pizza stone, fireplace stone, refractory surface, or masonry that stays below ~1,000°F.
🥇 Best for extremely hot stone: ThermoWorks Hi-Temp Industrial IR
If your stone can exceed 1,000°F, I'd step up to the Hi-Temp Industrial model. It reaches 1,400°F and has a 30:1 distance-to-spot ratio, meaning you can measure a relatively small area from farther away. It also has adjustable emissivity.
That is particularly attractive for wood-fired pizza ovens, refractory materials and kiln-type applications.
💰 Best value: TempPro TP450W / TP30W
The current testing/review landscape consistently puts inexpensive TempPro/ThermoPro-style guns near the top for pizza-stone use. The TP450W has dual lasers and 16:1 optics, while the TP30W has 12:1 optics and currently carries a 4.5/5 rating from 181 Home Depot reviews in the shopping data I found.
For ordinary 700–950°F stone, I wouldn't spend hundreds unless you need professional calibration/build quality.
🏭 Best professional option: Fluke 572-2
Fluke Corporation's 572-2 is substantially more expensive, but it's a true high-temperature industrial instrument: –22°F to 1,652°F, 60:1 optics, dual-laser targeting, and high/low alarms.
For a normal pizza oven, it's overkill. For industrial refractory stone, furnaces, kilns, or measurements from a substantial distance, the extra capability can be worthwhile.
One important caveat: emissivity
For stone, adjustable emissivity is highly desirable. IR thermometers don't directly measure temperature; they infer it from infrared radiation emitted by the surface. A thermometer assuming the wrong emissivity can give you a misleading reading, particularly on different stone finishes, glazed ceramics, metal, or partially reflective surfaces.
That's why I'd favor the ThermoWorks Industrial IR, TP450W/TP30W, or a comparable adjustable-emissivity industrial instrument over a cheap fixed-emissivity gun. ThermoWorks explicitly provides 0.1–1.0 adjustment for materials including stone and tile.
Bottom line:
Pizza oven / ordinary hot stone: TempPro TP450W or ThermoWorks Industrial IR
Best combination of quality + price:ThermoWorks Industrial IR
Stone routinely >1,000°F:ThermoWorks Hi-Temp Industrial IR
Professional/industrial use:Fluke 572-2
Avoid: IR guns topping out at 600–750°F if your stone can reach 800–1,000°F. Recent pizza-oven comparisons specifically recommend at least ~1,000°F of range for high-temperature stone.
If you tell me the approximate stone temperature (e.g. 500°F, 900°F, 1,500°F) and whether this is for a pizza oven, fireplace, kiln, or masonry, I can narrow this to the 3 best models for that exact application and current prices.
