Thermocouple 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, from heavy duty corkscrew probes to delicate fine sous vide needle probes. All of these sensors 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.
