環(huán)境試驗箱正確使用三要素簡戶新解

 上海簡戶儀器是目前國內(nèi)環(huán)境試驗箱重要廠家之一，公司擁有自主研發(fā)，有完整的檢測設(shè)備和檢測手段。規(guī)模可達(dá)到上海前3名。在眾多試驗箱 公司中，口碑和質(zhì)量都是。

公司地址：上海閔行都市路332弄鉑金科學(xué)園區(qū)，工廠：上海大葉公路簡戶產(chǎn)業(yè)園靠近東石公路 3-8號廠房。

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

        首先在做環(huán)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(shù)要熟悉，要對所使用的試驗設(shè)備的技術(shù)性能要熟悉，對設(shè)備的構(gòu)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(xì)閱讀試驗設(shè)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(shè)備的不正常運行從而引起試驗樣品的損壞，試驗數(shù)據(jù)的不正確。

        其次，合理選擇環(huán)境試驗箱試驗設(shè)備。為保證試驗正常進(jìn)行，應(yīng)該根據(jù)試驗樣品的不同情況，選擇合適的試驗設(shè)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(fā)熱試驗樣品的試驗，其體積應(yīng)不大于試驗箱有效容積的十分之一。對于不發(fā)熱試驗樣品其體積應(yīng)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(huán)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(yīng)該換一個更大一些的試驗箱，因為電視機(jī)在工作時要發(fā)散熱量。

        第三，正確放置試驗樣品。試驗樣品的安放位置，應(yīng)離開箱壁10cm 以上，對多個樣品應(yīng)盡量放在同一平面上。樣品放置應(yīng)不堵塞出風(fēng)口和回風(fēng)口，給溫濕度傳感器也應(yīng)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
Address: Shanghai Minhang City Road, Lane 332 Platinum Science Park Factory: simple households, Daye Road, Shanghai Industrial Park near the East Stone Road 3-8, plant.
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.
