Thermocouple plug mounted needle probes are ideal for penetrating solid or semi-solid product to measure the core temperature. TME penetration sensors are highly accurate and many come with super-fast 3 second response ThermaSprint technology. TME needle probes come in all sizes, and are compatible with all standard thermocouple thermometers. Choose between thermocouple types T and K - T type thermocouples are best for use with food as they have good accuracy, whilst K type is better for more general usage with their wide temperature range.
