Why is the high and low temperature alternating humidity chamber surrounded by water mist
The high and low temperature alternating humidity chamber can test the various performance indicators of components and materials of electronic and electrical products, automobiles and motorcycles, aerospace, marine weapons, universities, research institutions and other related products under high and low temperature (alternating) cyclic changes. The product has a wide temperature control range, and its performance indicators meet the technical conditions of the national standard GB10592-89 high and low temperature alternating humidity test chamber.
In practical operation, when operators observe through the observation window, water mist may appear. Where does this water mist come from? Will it cause harm to the use of the equipment? Next, the editor will introduce it to you:
Firstly, let's take a look at the reasons for the generation of water mist. According to the testing standards of high and low temperature alternating humidity chambers, the humidity can also be 20-98% in different humidity levels. If you want to do humidity testing, you must have a humidification system. This is not difficult to understand, just like buying a humidifier in a supermarket. When the humidity is below 50%, water mist will not be generated because the humidity is not high enough. When the humidity is above 50%, especially in high humidity testing laboratories where it is necessary to achieve 85% or less, water mist is inevitable, so there is no need to be too nervous.
Secondly, whether the test product will be affected during the testing process depends on whether the test chamber is suitable for humidity testing. It is said that the high and low temperature alternating humidity chamber uses the principle material of mirror stainless steel, as well as SUS304 mirror panel and 304 stainless steel materials, which have strong corrosion resistance and heat resistance. Therefore, as long as high humidity testing is carried out, it will not have a significant impact.
In use, if the device encounters a situation where the humidity does not rise, humidity is not added, or the humidity always displays 100% RH, the user needs to analyze it according to the specific situation:
1. Humidity does not rise or humidity is not added: 1) If the humidifying tube is damaged, it can be replaced;
2) The water level float for controlling humidification has not risen; 3) The humidification solid-state relay is damaged.
2. The humidity display shows 100% RH: 1) The gauze is abnormal, replace the gauze;
2) Refrigeration system malfunction, check the refrigeration system; 3) Abnormal water supply in the waterway system, check the waterway system.
