What is environmental testing?

Electronic devices and industrial products that we rely on every day are impacted by our environment in a number of ways, including temperature, humidity, pressure, light, electromagnetic waves, and vibration. Environmental testing analyzes and evaluates the impact that these environmental factors have on products in order to ascertain their durability and reliability.

    In addition to components, assembled vehicles undergo testing, where impacts of light and vibrations are checked in addition to temperature and humidity.

  • Aircraft

    Complex environments of varying pressure, temperature and humidity are recreated to produce a testing environment similar to high-altitude or air transportation.

  • Pharmaceuticals, Foods, and Cosmetics

    For these products, prolonged temperature and humidity testing are conducted to ensure their properties will not change after long-term storage.

  • Hypoxic Training

    Reduced oxygen conditions are created inside the test area to reproduce a low-oxygen environment similar to altitude training.
