⚠【NOT FOR HUMAN】THIS IS NOT A MEDICAL THERMOMETER,DO NOT USE TO TAKE TEMPERATURE OF BODY OR FOREHEAD. OnniOne digital infrared thermometer gun can't measure the internal temperature; Only work with surface temperatures.The measured temperature for humans will not be correct.

💡【Backlit Large Screen & Automatic Shutdown】OnniOne infrared cooking thermometer has a large screen,enables you to freely take the clearest temperature readings in all directions while aiming at an object.LCD backlight helps you view the temperature even in the dark! At the same time,this temperature gun will automatically shutdown after 6 seconds of being out of use,helping to save more power.

🚀【Non-contact for Multiple Uses & 0.5s Fast Read】Hands free technology makes this infrared thermometer ideal for objects that are out of reach,especially for those objects that would be dangerous to get close to or are moving.Just point,hold and keep it still to get accurate results in 0.5s! Measuring range of the IR gun -58℉ to 932℉,suitable for daily & industrial applications,such as pizza oven,blackstone,deep frying,car engines,A/C vents,planting & heating system maintenance.

High Temp Thermometer - When you’re smelting or heating your kiln up to cone 10, you don’t want a temperature probe that fails. Our instant read digital thermometer is perfect for DIY or commercial uses alike.

Two ways to measure - Use the 20-inch metal probe to take a quick reading of just how hot your furnace is, or you can run the insulated thermocouple wire into your wood-fired oven or gas kiln to take a reading. Both use a standard K-Type flat male/female connection.

Pairs perfectly with our other products - Designed to read temps in our GG series of furnaces, our CMF line of tough forges, or our smokeless fire pits. Requires one 9V, not included.
