Description
EDL’s Comparison Cryostat Calibrator (CRYO-CAL-2) is a passively cooled cryostat that allows the user to affordably calibrate temperature measurement devices from 77 K (-196 °C) to ambient. Using liquid nitrogen as the cooling media eliminates the extreme cost of cascade compressor systems and the cumbersome nature of such baths. Calibrating at 113 K (-160 °C) is no problem, and in fact, any temperature above 77 K (-196 °C) can be accomplished with dwell times greater than 15 minutes. The Cryo-Cal-2 requires no expensive bath fluids and is virtually maintenance free because there are no moving parts or pumping systems. With less than thirteen (13) liters of LN2, affordable comparison calibrations can be performed at any temperature above 77 K (-196 °C)!
