EA and EAH Series

Weiss Techniks' 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, with more than one condition 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. Weiss Technik will design a chamber to meet your specific needs. Note: EAH models are constructed with an internal pressure member. EA Models can be quoted with an external pressure member construction. View individual product features below and contact us for more information.
