From the trusted brand RS PRO, comes a range of high quality and great value thermocouple extension cables.
Manufactured to industry standards, these extension wires are an excellent solution for extending the distance between a temperature probe and the instrument that providing the reading.

Thermocouples are instruments that are designed to provide temperature measurement of substances and 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

Screened share a lot in common with unscreened cables however screened cables emit less electromagnetic energy which can cause signal interference with cables that are nearby.

A PT100 sensor is considered the most rugged and common form of an RTD (resistance temperature detector) and has a resistance of 100 ohms (Ω)

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.
