RS PRO NTC Thermistor Temperature Probe

Introducing the range of RS PRO high-quality NTC Thermistor Temperature Probes, ideal as a heavy-duty and high-accuracy solution for measurement of temperature in-between packaged goods. The probe has been designed with a straight handle for better and steadier control when measuring, ensuring reliable results, and features a 2 m long durable cable with a jack plug, offering quick and easy installation, especially when time and resource is limited. The probe has a robust stainless steel construction, suitable for use in harsh environments like industrial or commercial settings, whilst ensuring highly accurate and reliable measurements while being versatile enough to use in a wide range of applications.

Features and Benefits:

  • This range of RS PRO NTC thermistor temperature probes are ideal for high-accuracy and reliable measurement of temperature in-between packaged goods, generally in goods-in inspections or quality control environments

  • Each sensor has a wide operating temperature range: -50 °C to +150°C with a 85 x 3 x 5 mm probe and ±0.2⁰C (±0.15%) accuracy

  • The probe is made from rigid corrosion-resistant stainless steel for protection of the sensing element, while the flat probe tip allows quick measurement and inspection of packaged goods as well as liquids

  • Designed to be waterproof, the probe can withstand liquid ingress should it happen while measuring

  • Probe Length: 100 mm


Temperature probes are known for their robust design meaning they are ideal for use in many general-purpose industrial, commercial and scientific applications where accurate temperature measurement and monitoring are key and essential in ensuring equipment is functioning correctly or accurately measuring during testing and investigations. These sensor probes are often used in the following areas:

  • Air conditioning and refrigeration

  • Chemical industry

  • Plastics processing

  • Stoves and grills

  • Air, gas and liquid temperature measurement

  • Exhaust gas temperature measurement

  • Food processing

  • Laboratories

What is a Thermistor Probe?

A thermistor probe, although not suitable for very high temperature measurements, is designed to detect large changes in resistance within a relatively small or low temperature change. This is especially useful as they are more sensitive than most other temperature sensors or probes, meaning any small changes can be measured and recorded.
