Thermal Vial is designed for use with ultralow freezer, cryogenic storage and scientific storage applications to -452°F (-269°C). Temperature-sensing system fromMinco Products Inc.includes a precision RTD probe, match-calibrated 4 to 20 mA transmitter in a moistureproof enclosure, and flexible cable. The system's fluid-filled container allows simulation of the thermal response of the freezer contents. The container acts as a thermal ballast to delay reaction and prevent false alarms. It can be filled with cryoperservatives, alcohol, water or ethylene glycol solutions to accurately emulate the material being processed or stored. Unit is sealed to eliminate potential spillage and contamination of contents.
