Thermocouples are great for measuring the temperature in situations where a standard temperature probe would melt! While most standard temperature sensors will allow you to work up towards 125°C, the fiberglass braid insulation allows this sensor to be used in temperatures up to 500°C.

The probe itself is not enough to read the temperature; an amplifier will be required to read the incredibly small variation in voltage seen on a thermocouple. With this probe we recommend using Adafruit’s MAX31855 Breakout Board as it is easy to use and works great with the Raspberry Pi and most microcontrollers.

Please Note: There is a small piece of heatshrink on the end of this probe that prevents the fiberglass jacket from fraying that has to be removed when using in temperatures exceeding 250°C
