K-Type Thermocouple Set with MAX6675 0-800 °C

This set is used to measure high temperatures with an Arduino or Raspberry Pi. The MAX6675 evaluates the type K thermocouple and outputs the temperature via an SPI-compatible interface; the heat-resistant thermocouple with M6 thread is included. Only the probe is intended for high temperatures, the electronics belong in the range of -20 to 80 °C.

Recommended alternative for measurements below 0 °C: MAX31855K Thermocouple Breakout SparkFun

Features:
