Water-Cooled Programmable Altitude Test Chamber for Reliability and Stability Testing

 Water-Cooled Programmable  altitude test chamber for reliability and stability Testing 

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.
