For fast, precise temperature measurements: use the clamp probe (NTC) with the compatible measuring instrument (please order separately) to measure the surface temperature of pipes. Clamp probe (NTC) – equipment and areas of application Use the fixed cable to connect the clamp probe (NTC) to the measuring instrument (please order separately). The clamp probe is equipped with a high-quality NTC sensor and is easy to use. The clamp probe (NTC) is designed for measuring the surface temperature of pipes (pipe diameters from 6 to 35 mm) and offers numerous application options. For example, it is ideal for measuring flow and return temperatures on heating systems or for detecting superheating/subcooling on refrigeration systems.
