CRYO-CAL-2 Comparison Cryostat Calibrator CRYO-CAL-2 EDI Electronic Development Labs

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.
