The AX 131 are precision thermoelement temperature sensors of the type K. The penetration and immersion sensors are designed for use in gases, liquids and soft materials. The surface sensor variants are optimized for touching measurement on hard surfaces. The sensor tube is made of rust-free and temperature-resistant stainless steel, suitable for constant contact with food.The cable comes with a standardized miniature flat plug or loose ends.The sensors are based on class 1 thermal materials, the highest precision class for thermocouples. Caution! In practice, however, surface probes have greater deviations than specified in this class due to the temperature gradient at the contact point.This text is machine translated.
