Thermocouple Probes

Robust thermocouple probes for food and industrial applications. Immersion, surface and air options available. Designed and made in the UK.
Thermocouple Probes

Thermocouple probes are popular for their wide temperature ranges and fast readings. They're accurate, durable, and effective across a wide range of applications.

Response times for our probes are as fast as half a second. Temperatures go as low as -100 °C and as high as 1200 °C. Accuracy is typically under ±0.5 °C.

Thermocouples come with different types of connectors. We stock two of the most popular: K-type thermocouple and T-type thermocouple.

Our extensive range of thermocouples is tailored to a variety of uses, from internal food temperatures to pipe surfaces. For specialised applications where standard options aren't effective, we are able to manufacture bespoke sensors to meet your requirements.

Common thermocouple types

Penetration

Ideal internal measurements of liquids and semi-solids. Different options include ones with high or low temperature ranges and fast response times. Colour-coded handles are ideal for avoiding cross-contamination in food service. Needle probes are ideal for fine applications.

Surface

We have a range of sensors designed for measuring the temperature of different surfaces. Pipe probes are specifically tailored to enclosing around pipes for greater accuracy. Between-pack probes are ideal for checking food deliveries. Our ribbon surface probes use a unique technology that ensures fast, accurate results.

Air and gas

Our options for air and gas measurement include general purpose air sensors, oven probes, and wire probes designed for cold food storage. All are available with type T or type K thermocouple connectors.

Frequently Asked Questions

What is a thermocouple probe?

A thermocouple probe is a temperature sensor that measures temperature by using two different metals joined together at the probe tip. It is designed to connect to a compatible thermometer and provides fast, accurate readings across a wide temperature range.

What's the difference between Type K and Type T thermocouple probes?

Type K thermocouple probes offer a very wide temperature range, making them suitable for high-temperature applications such as ovens, grills, industrial processes and manufacturing. Type T thermocouple probes are particularly accurate at lower temperatures and are commonly used for food, refrigeration, laboratories and cryogenic applications.

Are Type K and Type T thermocouple probes interchangeable?

No. Type K and Type T probes use different metal combinations and generate different temperature signals. Always use a probe that matches the thermocouple type supported by your thermometer.

Which thermocouple probe should I choose?

The right probe depends on your application. Immersion probes are ideal for finding the core temperature of foods and liquids, air probes measure ambient temperature, surface probes are designed for grills and pipes, and wire probes are suited to ovens and continuous monitoring. Consider both the temperature range and the material you're measuring.

How do I recalibrate my thermometers and probes?

You can send your equipment to ETI’s UKAS calibration laboratory for accredited recalibration. We will return your instruments to you within their specified accuracy range and with a new calibration certificate.
