Precise Control with Chilled Mirror Accuracy

PGC and EdgeTech provide large volume calibration chambers that combine the quality and durability of the PGC line with the proven
technology of the EdgeTech hygrometer. These chambers are utilized for large volume calibrations, and testing/quality control applications requiring humidity and temperature control within very narrow tolerances.

When specific conditions are required, accuracy, constancy, and uniformity of an atmosphere must be considered. EdgeTech provides an accurate humidity and temperature measurement, while PGC maintains a precise control constancy and chamber uniformity.

Reach-in systems are equipped with a window in the outer door, a clear inner door, an iris opening (for making adjustments without an inner door opening), and a cable port.

Walk-ins can be custom sized and arranged with various shelving configurations. Cable ports, windows, and HEPA filtration are also available.

All units are equipped with a SmartPad controller which includes automatic ramping, alarms, and a digital communications port.
