Discontinued, Please See Our New Series 56 Probes
The Series 44 cryogenic temperature probes utilize either a 200Ω or 1000Ω platinum resistance thermometer (PRT), or a silicon diode (SD) thermometer and are constructed of stainless steel. The 44B design is designed for operation from -40°C to +200°C and the 44C from -196°C to +125°C. The Series 44 is also available with silicon diode sensing elements (54D) for operation in the most extreme cryogenic temperature regimes down to -269°C.
