5623B Series - Full immersion freezer PRT/RTD probes
: Use this probe when calibrating freezers, freeze dryers and other cold chambers. This unique freezer probe measures with ±0.05°C accuracy, even when its entire handle and cable are immersed in temperatures as cold as –100°C. Other PRTs will break when the entire assembly is exposed to the temperatures that this probe can handle.
