Environmental Resistance Testing for Automotive Industry

(Measuring temperature, humidity, vehicle speed using GL820)

Present day vehicles are used in various harsh environments due to the progression of the automotive technology available in the market
place. With that, the requirements for driving performances, safety, and comfort have increased and so to have the evaluation testing for
various stages in automotive development. Using the chassis dynamo test rooms, real world vehicle conditions are simulated and evaluat
ed in depth. These testings are crucial in improving the reliability for safety, pollution control, and energy saving measure
