EA & EAH Series

Temperature/Altitude/Humidity chambers are typically used to simulate test conditions for components and subassemblies designed to meet military specifications and/or for use in aeronautical, space engineering, automotive, computer, electronics, packaging, and meteorological fields.

Envirotronics' EA (temperature/altitude) and EAH (temperature/altitude/humidity) chambers are designed to allow the user to perform temperature, humidity, and altitude condition testing in one combined test chamber More than one condition can be created simultaneously to satisfy many types of test requirements. Our EA and EAH Series chambers are designed to simulate altitude conditions up to 100,000 ft. They are also designed to offer simultaneous temperature/altitude testing from site altitude to 65,000 ft. Humidity tests can be conducted at site altitude only.

The EA/EAH chambers are available in 8, 18, 27, 40, and 64 cu. ft. models. If your requirements fall outside the realm of these standard sizes, Envirotronics will design a chamber to meet your specific needs.
