RS PRO Type J Thermocouple 10m Length, 1/0.2mm Diameter → +260°C

Various types of exposed junction thermocouples with fitted miniature plug and insulated leads, ideal for test and develoment applications.

Thermocouple types K, J and T

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.

Type N sensors have a wide temperature range of -270°C to +1300°C. Type-N sensors exhibits lower susceptibility to oxidation than type K sensors under more extreme heat.

Type T sensors have a temperature range of −200°C to +350°C and are known to be especially stable thermocouple configurations.
