高低温冲击试验箱适用于航空、航天、军工、 电子、电工产品等模拟试品在大气温度急剧变化 条件下的适应性试验及对电子元器件的安全可靠 性试验和产品筛选。试验箱分为两箱式动态冲击和三箱式静态冲击，既可做高低温冲击试验，也可做单 独高温或低温试验。

The high and low temperature impact test chamber is suitable for the adaptability test of simulated test objects such as aviation, aerospace, military, electronic and electrical products under the condition of rapid change of atmospheric temperature, as well as the safety and reliability test and product screening of electronic components. The test chamber is divided into two-chamber dynamic impact and three-chamber static impact, which can be used for high and low temperature impact test, as well as separate high or low temperature test.

►两箱式：

Two boxes

分为上下、水平两种结构，采用气动机械装置进行转换，转换时间短，结构紧凑，体积小。

It is divided into two structures, up anddown,using pneumatic machinery for conversion,shortconversion time, compact structure andsmall volume.

►三箱式：

Three box type

通过气动系统控制的风门自动切换来实现温度转换，主要用于被测试样品在试验过程中必须静止不动以保证试品不受任何机械冲击。Thetemperature conversion is realized by theautomatic switching of the dampers controlledby the pneumatic system, which is mainly usedfor the tested sample, which must be stationaryduring the test process to ensure that the test product is free from any mechanical impact
