TRCIII

The TRCIII from Omega is an ice point™ calibration reference chamber and temperature reference probes, high precision base model. The TRCIII ice point™ calibration reference chamber relies on the equilibrium of ice and distilled, deionized water at atmospheric pressure to maintain 6 reference wells at precisely 0°C (32°F). The wells extend into a sealed cylindrical chamber containing the distilled, deionized water. The outer walls of the chambers are cooled by thermo-electric cooling elements. The increase in volume produced by the creation of ice crystals within the cell is sensed by the expansion of a bellows which operates a microswitch and controls the cooling elements. The automatic operational features of this instrument eliminate the need for frequent attention, required of common ice baths. On-off cycling of a pilot light indicates proper operation of unit at ice point temperature. Any combination of thermocouples may be used with this instrument.
