• For use with 1/4 to 1-1/3 in pipe

Testo NTC Clamp Probes will allow you to properly measure Evaporator and Condenser temperatures in real time using your Testo Digital Manifold. Using the clamp probes will also allow the manifold to calculate SuperHeat and SubCool values, ensuring that they are at a correct, optimized level, and the refrigeration system is running at maximum efficiency.
