Laboratory Vacuum Climate Chamber Low Pressure Temperature Altitude Chamber


Electrical Temperature Humidity Low Pressure Altitude Chamber is used in different industries like the instruments and meters, electrical products, materials, spare parts, equipment, etc, but mainly in aviation, aerospace, information, electronics and other industries. This machine can be operated at a low pressure, high temperature, low temperature, under the effect of single factor or multiple conditions at the same time. Simulation of high-altitude conditions like might be found in mountainous regions. Test for electric performance parameters of the specimen.
