Thermistor Probes

A core part of ETI’s probe range is the Thermistor probe series. These probes are unique in that the have a negative temperature co-efficient – this means they experience a decrease in electrical resistance when their temperature is raised. Thermistor probes are not recommended for the measurement of surface temperatures but are ideal for working in sub-zero temperatures (down to -40 °C) due to the PVC and fluoroethylene-propylene leads that can be used to manufacture them. Where requirements cannot be met from the existing standard range of probes, alternative designs can be manufactured.

Common thermistor probe types

Penetration

Perfect for measuring the internal temperature of liquids and semi-solids with high accuracy. Available in waterproof, fast response and colour-coded options to suit varying applications. Ideal for food safety, medical, and laboratory use where precision is essential.

Between-Pack

Designed for checking the temperature of packaged goods, ensuring food safety during storage and transport. These probes slide easily between boxes or vacuum-sealed packs to provide accurate readings without opening the packaging.

Slow Response

Dampened air and food simulant probes are designed to mimic product temperatures rather than react to rapid air fluctuations. Ideal for cold storage and food safety monitoring, they help maintain accurate temperature control.
