Four selection principles for temperature and humidity environmental Test Chambers

Abstract: 本文讲述了选择温湿度环境试验箱时的四个关键原则。首先,环境试验箱必须能够在一定的公差范围内准确再现自然环境条件,以确保测试结果的真实有效。再有就是试验箱需提供环境条件的高可重复性,以便在不同的设备和多次测试中获得可比的结果。第三,环境参数必须可控和可观察,以确保测试过程中环境条件的稳定性和安全性,并防止因条件失控造成的损坏。最后,试验箱的安全性和可靠性也尤为重要,应具备操作安全、方便、可靠等特点,以及完善的保护和报警系统,以确保测试人员和设备的安全。

The temperature and humidity environmental chamber, also known as the climate chamber, is an environmental simulation system and equipment commonly used in laboratories and factories. The environmental Test Chamber is used to test the performance stability of materials or products in various environments by simulating natural environments such as high temperature, low temperature, humidity, and dryness. So how to choose a suitable temperature and humidity Environment Chamber?

selection principle

  • Reproducibility of environmental conditions

It is very difficult to completely and accurately reproduce the environmental conditions of nature in the laboratory. However, within a certain tolerance range, people can approximately simulate the external environmental conditions experienced by engineering products during use, storage, transportation, etc. Only in this way can the reproducibility of the environmental conditions in the environmental test be guaranteed.

  • Repeatability of environmental conditions

An environmental Test Chamber can conduct multiple tests on the same product, and the same product under test can also be tested in different environmental Test Chambers. In order to ensure that the test results obtained by the same product under the same test environmental conditions are comparable, the environmental conditions provided by the environmental Test Chamber must have the required repeatability.

  • Controllability of Environmental Parameters

The environmental conditions provided by any environmental Test Chamber need to be observable and controllable, not only to limit the environmental parameters within a certain tolerance range, thereby ensuring the reproducibility and repeatability of the required test conditions, but also Also starting from safety. Product testing is necessary to prevent uncontrolled environmental conditions from causing product damage and unnecessary losses. At present, various test specifications require that the accuracy of parameter testing should not be lower than one-third of the allowable error of the test conditions.

  • Test instrument safety and reliability

Environmental testing, especially reliability testing with a long test cycle, during the testing process, Testers often have to go to the site to check the testing work, so the requirements for environmental testing equipment need to be safe to operate, easy to operate, reliable to use, long working hours, etc. features. Characteristics such as lifespan guarantee the normal operation of the test itself. The test equipment for various protection, alarm measures and safety interlocking devices should be perfect and reliable to ensure the safety and reliability of Testers, tested products and test equipment itself.
