高低溫沖擊試驗箱適用于航空、航天、軍工、 電子、電工產品等模擬試品在大氣溫度急劇變化 條件下的適應性試驗及對電子元器件的安全可靠 性試驗和產品篩選。試驗箱分為兩箱式動態沖擊和三箱式靜態沖擊，既可做高低溫沖擊試驗，也可做單 獨高溫或低溫試驗。

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.

?兩箱式：

Two boxes

分為上下、水平兩種結構，采用氣動機械裝置進行轉換，轉換時間短，結構緊湊，體積小。

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

通過氣動系統控制的風門自動切換來實現溫度轉換，主要用于被測試樣品在試驗過程中必須靜止不動以保證試品不受任何機械沖擊。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
