TRCIII-A shown smaller than actual size.
The ice pointTM TRCIII-A Calibration Reference
Chamber is part of OMEGA’s fine line
of calibration reference instrumentation.
The TRCIII-A ice pointTM 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). 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 microswitch and controls the cooling
elements. The alternate freezing and thawing of the
ice accurately maintains a 0°C (32°F) environment
around the reference wells.
