Frequently asked questions
How do I read it with an Arduino?
Use a K-type thermocouple amplifier such as the MAX6675 or MAX31855 and connect its inputs to the probe leads, observing polarity. The amplifier outputs a digital reading that the Arduino can read.
Can I measure above 400 °C with it?
No. The listed range is 0–400 °C, and exceeding it can damage the probe and its insulation.
