    • 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 probe thermometer for furnaces is perfect for DIY or commercial use 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 2 AA batteries, not included. 
    • K-Type Thermocouple - Fast & reliable, K-type is the go-to device when measuring high temperatures. Our extra-long 50 cm metal probe can quickly measure high temps of up to 2370°F.
