RS PRO Type K Thermocouple 1/0.3mm Diameter → +350°C

From RS PRO, comes a range of type K and J glass fibre exposed thermocouples. With a probe that has been constructed with glass fibre for added flexibility, strength and easy to use, these thermocouples are a fantastic solution for temperature measurement.

Thermocouples have a variety of applications such as;

• Medical - research into DNA and hypodermic insertion to detecting a tumour.


• Vehicle diagnostics - used to monitor and adjust factors such as battery health, exhaust readings, spark plug function and brake performance.


• Temperature readings in boilers, heating sensors, and ovens


• Food thermometers, industrial probes, and sensors

Type K sensors, which typically have a temperature range from -200 to +1260°C, are known to be commonly used in a variety of industries and sectors. Type K sensors are also very accurate and reliable across wide ranges of operating temperatures.

Type J sensors have a narrower temperature range from -40°C to +750°C. If they are regularly exposed to more excessive heat, they experience a shorter lifespan. Type J sensors are considered to be very versatile and are ideal for taking readings from a range of older types of equipment.
