The working principle of the constant temperature and humidity test chamber and the walk-in constant temperature and humidity room are the same. The Kunshan Haida instrument has production, but there are still some differences in the scope of use and structure. Let's take a look at what's different. 1. Scope of application: The constant temperature and humidity test chamber is suitable for the reliability test of product sampling or products with relatively large volume. The walk-in constant temperature and humidity room is suitable for product batch inspection or reliability testing of relatively large products. 2, structure: constant temperature and humidity test box, the general inner box is made of imported SUS304? stainless steel mirror panel, the wall is resistant to high temperature, the shell is made of high quality cold rolled sheet or SUS304# embossed stainless steel, and the surface phosphating electrostatic spray is treated with high temperature. . The walk-in constant temperature and humidity room is generally made of SUS304? stainless steel plate and the outer shell is made of color steel plate. 3. Appearance: The constant temperature and humidity test chamber is generally integrated, that is, the refrigeration system, the heating system, the wind circulation system, and the waterway system are all installed inside the casing. The walk-in constant temperature and humidity room is generally separated by the box and the control system. . That is, the control system is generally installed outside the box. 4. Volume: The walk-in constant temperature and humidity room has a relatively large volume and a constant temperature and humidity test chamber, and the installation space requirements are relatively large. 5. Production: The step-in constant temperature and humidity room has a longer production cycle than the constant temperature and humidity test chamber, and the constant temperature and humidity test chamber can be directly delivered to the customer for installation and debugging, and the walk-in constant temperature and humidity room is used. It can be assembled and debugged at the customer's designated location before it can be used. 6. Cooling method: The constant temperature and humidity test chamber is generally air-cooled, and the walk-in type is generally water-cooled. 7. Price: The walk-in constant temperature and humidity room is much higher than the constant temperature and humidity test chamber. 8, power: step-in constant temperature and humidity room is generally in the three-phase 20KW-50KW, constant temperature and humidity testing machine is much smaller.
