The main points of choosing constant temperature and humidity box Summarizing some common problems and blind spots encountered by customers in the inquiry and purchase process of constant temperature and humidity boxes, the editor summarizes the following basic points to provide new and old customers as a reference for the purchase guide: 1. Size The size of the constant temperature and humidity box depends on the size of the test product. According to the requirements of the national standard GB2423, the size of the test studio should be greater than or equal to 3 times the test product, so the test effect is the most ideal, such as products The size is 300 width 250 length 180 height MM. If the number of test products is not large, 408L (studio 600X850X800MM) is enough. Of course, you can choose a larger volume, which can be tested in multiple layers; Second, the choice of power supply Constant temperature and humidity box whether it is 220V or 380V are three-phase or more power supply, if the temperature is below -40 degrees, and the box is more than 225L, it is recommended to choose 380V four-phase power supply excuse, because of the use of the experimental box Electricity is relatively stable; 3. Condensation method: Air-cooled and water-cooled constant temperature and humidity boxes are generally used. Air-cooled is generally used. Water-cooled is usually a large constant temperature and humidity chamber or a large box rapid temperature rise and fall test machine. Generally, cold and heat shock test boxes are used. More water cooling; 4. The environment of constant temperature and humidity box (1).
