DescriptionThe new ice point™ reference chamber TRCIII-A is the latest addition to OMEGA’s fine line of calibration reference instrumentation. The TRCIII-A 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. Each well extends into a sealed cylindrical chamber containing the distilled deionized water. The outer walls of the chamber are cooled by thermoelectric 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 micro switch and controls the cooling elements. The alternate freezing and thawing of the ice accurately maintains a 0°C environment around the reference wells. The TRCIII-A has a built in temperature readout [°C/°F] with 0.1° resolution. The unit comes with a NIST-traceable calibration certificate.
