An environmental chamber, also called a climatic chamber or climate chamber, is an enclosure used to test the effects of specified environmental conditions on biological items, industrial products, materials, and electronic devices and components.

Environmental Chamber are used extensively in various industries to test products before they are introduced to the market. The aerospace industry uses climate chambers to test equipment in accordance with the Radio Technical Commission for Aeronautics (RTCA) DO-160 standards, which include thermal and vibration aging tests. The automotive industry also relies on climate chambers to test new technologies for viability. The pharmaceutical industry uses climate chambers to conduct stability and stress tests to determine drug expiration dates and how they function during temperature changes and exposure to ultraviolet rays. Cosmetics are tested for stability using temperature, humidity, and light, while food and beverage industries use climate chambers to test shelf life under controlled conditions. Climate chambers are also used to test packaging materials and touch-sensitive instruments for long-term exposure to adverse environmental conditions.
