Below is a list of AGREE Chambers manufacturers from Tempe, Arizona. AGREE chambers are those originally designed by a military consortium to test military equipment under certain environmental conditions in the 1980s to ensure reliability and durability of their equipment. The Department of Defense Advisory Group on Reliability of Electronic Equipment originally designed the method of testing to conform to military specific standards. Today, AGREE test equipment is still used to perform reliability, qualification and environmental stress screening (ESS) but rather for many industries including electronics, automotive and telecommunications equipment.
