Model 5623A Freezer Probe can be placed within a dry or wet environment of -328 to 312oF (-200 to 156oC). The assembly is sealed to prevent the introduction of moisture when exposed to extremely low temperatures. Designed as a calibration standard, the probe has an accuracy (which includes calibration uncertainty and short-term stability) of +/-0.05oC over its range. Each probe is supplied with a NIST-traceable certificate of calibration and specific ITS-90 coefficients. It is available in a 0.25" dia. by 6" long Inconel sheath.
