Below is a list of Altitude Chambers manufacturers from Cedar Park, Texas. Altitude chambers, or hypobaric chambers, are environmental test chambers which replicate the pressure and gas conditions found at differing altitudes for the purposes of evaluating the response to the changes. Altitude chambers are used to test electronics, products and packaging which may be exposed to high altitude environments during their lifespan. If malfunctions occur, or other flaws are revealed in the testing process, manufacturers can then adapt the product design to avoid future malfunctions.
