Integrated Low Pressure Test Chamber
Purpose:
It is mainly for the testing of the environment adaptability and reliability of the instruments and meters,electronic instruments ,materials and components in low-pressure,high-temperature and low-temperature under the condition of single or multiterm, and for the testing of electric parameters in the meantime.
Standard Configuration:
A copy of the instruction and test report for the product, A certificate and quality assurance.2 Shelf and 4 shelves .
Remark:1,The hanging touch screen(240mm) has not including in the width of exterior dimension;2,water-cooled(water temperature 10-28℃,hydraulic pressure 0.1-0.3MPa,to ensure the cooling performance);3, The function of fast step-down for Optional.;4,The function of heating and humidification for optional.
