Low Pressure Test Chamber under High and Low Temperature Machine 150L
Equipment Usage
The high and low temperature and low pressure test chamber is used to simulate the climate of high altitude, high altitude areas (plateau areas) for storage, operation, and transportation reliability tests. It can simultaneously conduct electrical performance parameter tests on test specimens while they are powered on. It is applicable to national defense industry, aerospace industry, automation components, automotive parts, batteries, flat panel display groups, industrial and related product materials for high temperature, low temperature, altitude (not higher than 30,000 meters or 45,000 meters above sea level), high and low temperature cycle tests, temperature and altitude comprehensive tests. When conducting high and low temperature tests, this test chamber can be used for tests on heat - dissipating and non - heat - dissipating test samples.
