An Unsurpassed RH Control of ±0.5%

The PGC 30 cu. ft. chamber features our unique humidity control system that enables the user to attain unsurpassed levels of relative humidity/temperature control and uniformity.

These test chambers are designed to accurately produce those temperature and humidity conditions required for applications such as stability studies, package testing, TAPPI, MIL-SPEC, and vapor tranmission.

RH Variables PGC, Inc. Competition
Control Constancy ± 0.5% ± 2.0%
Chamber Uniformity ± 0.5% ± 2.0%
Sensor Accuracy ± 1.0% ± 2.0%
Total ± 2.0% ± 6.0%

Applications are found in such diverse industries as pharmaceutical development and manufacturing, electronic components, food, semiconductor, paper and pulp, and wherever precise humidity and temperature replications are required.

Additionally, PGC's SmartPad microprocessor controller is a user-friendly system that provides optimum accuracy and control. The SmartPad is equipped with direct readings in both temperature and humidity. It also features 60-segment programming for automatic cycling and ramping and soaking excursions. High-low or deviation alarms as well as digital communications ports are standard features.

The interior chamber is constructed of very durable, corrosion resistant 316 stainless stell. Low watt density heaters are used that also contribute to the unit's longer life.

Should your application require it, the chamber air flow can be factory-configured from the standard horizontal flow to vertical. Other options include extended ranges, chart recorders, a window in the outer door, and a clean inner door with optional iris opening.

Lastly, all PGC equipment is exhaustively tested at your specified condition before being shipped to ensure trouble-free operation.
