The Omega TRCIII Ice Point Reference Chamber relies on the equilibrium of ice and distilled, deionized water at atmospheric pressure to maintain six reference wells at precisely 0 C. The TRCIII wells extend into a sealed cylindrical chamber containing the distilled, deionized water.

The outer walls of the TRCIII 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 alternate freezing and thawing of the ice accurately maintains a 0C environment around the reference wells.
