Hard To Find Used Thermotron Altitude Test Chamber!

Altitude Test Chambers are used to simulate various altitudes on a product.  They subject a product to various levels of altitude up to 100,000 ft. with the option of extending the range. Designed to simulate Altitude, Temperature, and Humidity Environments, these chambers are commonly used in Defense, Aerospace, Aviation, and Electronic Industries. Also a required item for any well equipped Test Lab.
