268 TRCIII-A £990 All Models ice point™ Calibration Reference Chamber High Precision Thermoelectric Chamber Uses Water to Maintain 0°C Continuously The ice pointTM TRCIII-A Calibration Reference Chamber is the latest addition to OMEGA’s fine range of calibration reference instrumentation. The TRCIII-A ice pointTM Reference Chamber relies on the equilibrium of ice and distilled, deionised water at atmospheric pressure to maintain 6 reference wells at precisely 0°C. Each well extends into a sealed cylindrical chamber containing the distilled deionised 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 microswitch and Probes sold separately; please see page 275 TRCIII-A, £990, shown smaller than actual size. controls the cooling elements. The alternate freezing and thawing of the ice accurately maintains a 0°C environment around the reference wells. OMEGACARESM extended warranty programme is available for models shown on this page.
