RS PRO Type K Rubber Patch Thermocouple 5 m Length, 1 mm Diameter, 750 °C Minimum Temperature, 150 °C Maximum 239-4675

RS PRO 239-4675 Type K Rubber Patch Thermocouple is a high-quality surface temperature sensor designed for industrial and laboratory applications. It features a 5 m long cable with 1 mm diameter twin-twisted wires insulated with durable PFA, terminated with a bare wire tail for versatile connection. The thermocouple adopts JIS Type K standards, providing reliable measurements within a range from 750 °C minimum temperature sensing to a maximum of 150 °C.

The sensor includes a self-adhesive silicone rubber patch (40 mm x 13 mm x 5 mm) that allows firm attachment directly onto surfaces, enabling accurate surface temperature monitoring even on irregular or curved substrates. The sensor’s construction offers excellent chemical and oil resistance, ensuring durability in demanding environments.

Thermocouples operate based on the Seebeck Effect, where two dissimilar metals joined at junctions produce a voltage corresponding to temperature difference. This makes the RS PRO thermocouple ideal for heat exchangers, power stations, brick and cement kilns, heat treatment processes, annealing furnaces, thermostats, food industry applications, vehicle diagnostics, and scientific laboratories.

Provides precise surface temperature measurements using JIS Type K thermocouple technology. Self-adhesive silicone rubber patch enables easy and secure mounting on various surfaces. Durable PFA insulated twin-twisted wires ensure reliable signal transmission over 5 meters.

Operates in temperature range from 750 °C minimum to 150 °C maximum. Compatible with uneven or curved surfaces due to flexible patch design. Resistant to many oils and chemicals for industrial durability. Bare wire tail terminal allows flexible connection options.

Ideal for industrial, laboratory, HVAC, and manufacturing surface temperature monitoring. Patch dimensions: 40 mm length x 13 mm width x 5 mm thickness. Manufactured in the United Kingdom ensuring quality and standards compliance.

This thermocouple is part of the RS PRO series, providing a robust solution for precise temperature measurement needs in various industrial sectors. For more options, other lengths (1 m and 2 m) are also available under related model stock numbers.
