　　GB/T 2423.4-2008This section is applicable to determining the adaptability of components, equipment, or other products to use, transport, and store under high humidity and temperature cycling conditions that typically result in condensation on the surface of the test sample. If this experiment is used to test the performance of packaged samples during transportation and storage, the test should be conducted together with the packaging.GB/T 2423.4-2008Constant temperature and humidity test chamber, also known as environmental testing machine, is used to test the heat resistance, cold resistance, dry resistance, and moisture resistance of various materials. Suitable for use in factories such as electronics, electronics, food, vehicles, metals, chemicals, and building materials.

Mixing system: using a long axis fan motor and a stainless steel multi blade impeller that is resistant to high and low temperatures to achieve strong convection and vertical diffusion circulation; Double layer high tensile sealing strips with high temperature resistance are used between the door and the box to ensure the sealing of the testing area; The observation window is made of multi-layer insulated tempered glass, with a laminated conductive film on the inner side (allowing for clear observation of the test process); Test holes (on the left side of the machine) are 50mm each (imported original) and can be used for external testing of power or signal lines. The aperture or number of holes should be increased as indicated.
