環境試驗箱儀器設備仍是一種精密、貴重設備。正確使用和操作環境試驗設備不僅能為檢測人員提供準確的依據，而且能使環境試驗設備長時間的正常運行和延長其設備的使用壽命。

        首先在做環境可靠性試驗時，對所需試驗的樣品性能、試驗條件、試驗程序和試驗技術要熟悉，要對所使用的試驗設備的技術性能要熟悉，對設備的構造要有所了解，尤其是對控制器的操作及性能要熟悉。還要仔細閱讀試驗設備的操作使用手冊，這樣可以避免因操作失誤而引起試驗設備的不正常運行從而引起試驗樣品的損壞，試驗數據的不正確。

        其次，合理選擇環境試驗箱試驗設備。為保證試驗正常進行，應該根據試驗樣品的不同情況，選擇合適的試驗設備，試驗樣品和試驗箱的有效容積之間也要保持一個合理的比例。

對于發熱試驗樣品的試驗，其體積應不大于試驗箱有效容積的十分之一。對于不發熱試驗樣品其體積應不大于試驗箱有效容積的五分之一。比如，一臺21`彩電在做溫度儲存試驗時，選用一個一立方體積的環境試驗箱就能滿足要求，而在通電工作時，它就不能滿足要求了，應該換一個更大一些的試驗箱，因為電視機在工作時要發散熱量。

        第三，正確放置試驗樣品。試驗樣品的安放位置，應離開箱壁10cm 以上，對多個樣品應盡量放在同一平面上。樣品放置應不堵塞出風口和回風口，給溫濕度傳感器也應留出一定距離。以保證試驗溫度的正確。

Shanghai  Jianhu  equipment ( :021-62,968,991) is one of the important manufacturers of domestic environmental chambers, the company owns the patent and complete testing equipment and testing methods. The scale can be achieved Shanghai 3. The reputation and quality are among the best in many chamber www.shjianhu。。ｃｏｍ company. 021 -62968993 : global toll-free hotline : website: www.shjianhu。。ｃｏｍ

The chamber equipment is a sophisticated, expensive equipment. The proper use and operation of environmental testing equipment () can not only provide an accurate basis for the testing personnel, and make environmental testing equipment uptime and extend the life of their equipment.
        First tests on the sample performance of the required tests, test conditions, test procedures and test techniques to be familiar with, to be familiar with the technical performance of the test equipment used to understand the structure of the device. In particular, be familiar with the operation and performance of the controller. Also carefully read the operating manual of the test equipment, to avoid causing damage to the test sample due to operational errors caused by the normal operation of test equipment, test data is not correct.
        Second, a reasonable choice of the environmental chamber (testTo ensure that the test is normal, should be based on the different circumstances of the test sample, select the appropriate test equipment, test samples and the effective volume of the chamber have to keep a reasonable proportion.
Heating test sample test, its size should not exceed one tenth of the effective chamber volume. Not heat the test sample volume should be not more than one fifth of the chamber effective volume. For example, a 21 'color TV in temperature storage test, the choice of a cubic volume the chamber www.jianhutest。。ｃｏｍ will be able to meet the requirements of work in the power, it can not meet the requirements, it should be a greater some of the chamber, because the TV at work to diverge heat.
        Third, the correct placement of the test sample. The placement of the test sample, should leave the walls of the box than 10cm, multiple samples should be placed in the same plane. Place the sample should not be clogging the outlet and return air temperature and humidity sensor should set aside a certain distance. To ensure that the correct test temperature.
