環(huán)境試驗(yàn)箱正確使用三要素簡(jiǎn)戶新解

 上海簡(jiǎn)戶儀器是目前國(guó)內(nèi)環(huán)境試驗(yàn)箱重要廠家之一，公司擁有自主研發(fā)，有完整的檢測(cè)設(shè)備和檢測(cè)手段。規(guī)?？蛇_(dá)到上海前3名。在眾多試驗(yàn)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(jiǎn)戶產(chǎn)業(yè)園靠近東石公路 3-8號(hào)廠房。

環(huán)境試驗(yàn)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(yàn)設(shè)備不僅能為檢測(cè)人員提供準(zhǔn)確的依據(jù)，而且能使環(huán)境試驗(yàn)設(shè)備長(zhǎng)時(shí)間的正常運(yùn)行和延長(zhǎng)其設(shè)備的使用壽命。

        首先在做環(huán)境可靠性試驗(yàn)時(shí)，對(duì)所需試驗(yàn)的樣品性能、試驗(yàn)條件、試驗(yàn)程序和試驗(yàn)技術(shù)要熟悉，要對(duì)所使用的試驗(yàn)設(shè)備的技術(shù)性能要熟悉，對(duì)設(shè)備的構(gòu)造要有所了解，尤其是對(duì)控制器的操作及性能要熟悉。還要仔細(xì)閱讀試驗(yàn)設(shè)備的操作使用手冊(cè)，這樣可以避免因操作失誤而引起試驗(yàn)設(shè)備的不正常運(yùn)行從而引起試驗(yàn)樣品的損壞，試驗(yàn)數(shù)據(jù)的不正確。

        其次，合理選擇環(huán)境試驗(yàn)箱試驗(yàn)設(shè)備。為保證試驗(yàn)正常進(jìn)行，應(yīng)該根據(jù)試驗(yàn)樣品的不同情況，選擇合適的試驗(yàn)設(shè)備，試驗(yàn)樣品和試驗(yàn)箱的有效容積之間也要保持一個(gè)合理的比例。

對(duì)于發(fā)熱試驗(yàn)樣品的試驗(yàn)，其體積應(yīng)不大于試驗(yàn)箱有效容積的十分之一。對(duì)于不發(fā)熱試驗(yàn)樣品其體積應(yīng)不大于試驗(yàn)箱有效容積的五分之一。比如，一臺(tái)21`彩電在做溫度儲(chǔ)存試驗(yàn)時(shí)，選用一個(gè)一立方體積的環(huán)境試驗(yàn)箱就能滿足要求，而在通電工作時(shí)，它就不能滿足要求了，應(yīng)該換一個(gè)更大一些的試驗(yàn)箱，因?yàn)殡娨暀C(jī)在工作時(shí)要發(fā)散熱量。

        第三，正確放置試驗(yàn)樣品。試驗(yàn)樣品的安放位置，應(yīng)離開(kāi)箱壁10cm 以上，對(duì)多個(gè)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(yàn)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.
