Climate chambers differ vastly in size ranging from walk-in chambers to small chambers. Most climate chambers are equipped with video feeds, allowing the operator to observe the product or component during the testing process. Reach-in chambers allow for the tester to manually adjust or change some conditions during the test. Climate chambers come with many different control options like modern digital readouts with LCD displays, simple analog indicators, or even automated and programmable control systems.
Environmental test chambers are designed with the capacity to replicate extreme environmental conditions in order to comprehensively test the reliability of a product. Altitude chambers simulate extremely high altitudes to evaluate the effects of pressure and air change, and routinely 10-8 Torr levels are achieved in these vacuum chambers.
Altitude chamber manufacturers fabricate chambers which have the capacity to replicate pressure conditions of up to 100,000 feet above sea level. Test chambers can be used to test a combination of environmental conditions, and often temperature and humidity tests are included in the altitude chamber.
This is necessary to increase the validity of the results in accordance to the true nature of the environment the product will be functioning in. Chambers such as these that designed for such extreme altitude testing must be equipped with heavy gauge walls to prevent the internal collapse of the structure due to the inside chamber's vacuum-like atmosphere. Chambers for altitude testing vary greatly in size from bench-top chambers to drive-in chambers due to the broad range of products that require altitude testing.
