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.
