High and Low Temperature Test Chamber Low air pressure ▪ virtual space environment High/low Temperature Low Pressure Test Chamber It is mainly used in aviation, aerospace, information and electronic fields to determine the environmental adaptability and reliability of instruments, electrical engineering products, materials, parts and equipment in independent or composite environment of low air pressure, high temperature and low temperature; it can also be used to measure the electrical performance parameters of the test specimens. Forced ventilation ▪ balanced temperature ▪ fast response Adopts the method of forced blowing and circulation through rear side air channel and air supply through top side window. Air in the working room moves in the way of turbulent flow, meeting the requirements of temperature uniformity. Composite structure ▪ superior functionalities ▪ well designed Introduces integrated composite structure, that is, test chamber consists of the front incubator (bearing structure), the rear refrigeration, vacuum units and electrical controller (system) installed on the door of the test chamber. Electrical control panel is set on the front door of test chamber for convenient operation. Composition of vacuum system Vacuum system is a part used to measure and control vacuum degree, including vacuum measurement system and vacuum obtaining unit. The vacuum pump is 2XZ-15B (theoretical pumping speed: 15L/s) direct rotary vane vacuum pump manufactured by Shanghai First Company.
