RS PRO Type J Grounded Thermocouple 40mm Length, 4.76mm Diameter → +350°C

From RS PRO, comes a range of type K and J grounded tip thermocouples. Manufactured with a high-quality glass fibre stainless steel lead 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.

RS PRO is our own brand of high-quality products whilst bringing you great value for money. Our wide range of products have been engineered to meet high industry standards, so you are ensured reliable and robust solutions.
