# Associated Environmental Systems
> Associated Environmental Systems (AES) designs and manufactures precision
environmental test chambers in the United States. Its chambers simulate
temperature, humidity, thermal shock, and related conditions so manufacturers can
validate product reliability before release. AES serves the aerospace, defense,
automotive, battery, pharmaceutical, and electronics sectors with standard,
in-stock, custom, and rental chambers, backed by calibration, maintenance, and the
AESONE CONNECT remote monitoring platform.
## Test Chambers
