Industrial Altitude Environment Test Chamber for environmental stress screening

 Industrial Altitude Environment Test Chamber  for environmental stress screening

High Altitude Simulation Test Chambers test for the instruments and meters, electrical products, materials, spare parts, equipments, etc at a low pressure, high temperature, low temperature, under the effect of single factor or multiple factors at the same time. Simulation of high-altitude conditions like might be found in mountainous regions. Test for electric performance parameters of the specimen. Mainly used in aviation, aerospace, information, electronics and other industries.
