High Low Temperature/Low Air Pressure Test Chamber
High Low Temperature/Low Air Pressure Test Chamber is mainly used in aviation, aerospace, information, electronics and other fields, to ensure the environment adaptability and reliability of instruments , meters, electrical products, materials, parts, equipment in low temperature and low air pressure, or low temperature or low-high temperature and low air pressure, and measure the specimen’s technical parameters.
1.Perfect case structure, can undertake air pressure, stainless steel inner case.
2. Reasonable air cycle system and heater,refrigerator device.
3.Imported refrigeration units, key parts are international brands, improve the operation reliability.
4.Controller adopts touch screen man-machine interface, reliable operation, high precision.
5.Protection device for studio over-temperature, compressor over-load, over-pressure, oil pressure over-pressure ,fan over-load, default-phase, compressor delay.
