Introduction:
The low-pressure test chamber is mainly used to test the environmental adaptability and reliability test of the workpiece under low pressure, high temperature and low temperature single or simultaneous action, or to measure the electrical performance parameters of the test piece at the same time.
Application:
The test chamber is ideal for aviation, aerospace, electronics, national defense, scientific research and other industrial departments to determine electrical and electronic products (including components, materials and instrumentation) under the single or simultaneous action of high, low temperature and low pressure, to carry out storage and transportation reliability test, and to test electrical performance parameters of the test products at the same time, in order to conduct the test products under given environmental conditions. The performance is evaluated.
Structure Features:
1. Internal pressure box, SUS304 stainless steel inner tank.
2. Multiple protection facilities, equipped with wireless remote alarm device
3. Double door sealing structure, adjustable locking mechanism.
4. Refrigeration compressor and key accessories are imported international famous brand, long-term reliable operation; environmental refrigerant refrigeration, meets the requirements of international environmental protection conventions.
