EA Series Altitude Test Chamber

The EA Series Altitude Test Chambers are expertly designed to simulate real-world conditions for products exposed to varying altitudes and temperature extremes. Capable of replicating altitudes up to 100,000 feet, these chambers allow users to control both temperature and humidity, providing a comprehensive testing environment. This combination is essential for evaluating the performance and reliability of components in industries such as aerospace, defense, automotive, and electronics, where products must endure significant pressure changes and climatic variations.

We offer vast experience designing altitude chambers with pre-engineered sizes from 18-55 cu. ft. and custom-designed solutions to meet your specific testing needs. The chambers are built to maintain precise control over environmental conditions, ensuring accurate altitude simulation to help identify potential failures early in the product development process. Our altitude chambers feature robust construction and may be designed with internal or external pressure members. These chambers not only deliver high performance but also ensure longevity and ease of maintenance, making them essential for manufacturers committed to quality assurance and product reliability.
