Product use: The constant temperature and humidity test room can be used to store a large number of items to be tested simultaneously for reliability test, so as to shorten the total test time of a single product. Or the temperature and humidity stress screening of the products, the need for large dynamic test space and the larger size of the products are suitable for this equipment. Structural characteristics: The constant temperature and humidity Test Room can provide large parts, semi-finished products and finished products for temperature and humidity environmental testing. It is mainly composed of control panel, distribution panel, heat preservation storage board, blower, heater, humidifier and freezer. The main specifications are divided into seven standard indoor dimensions and 28 test specifications under different conditions. With the combination of storehouse board unit, the internal volume can be enlarged arbitrarily, the disassembly is easy, the design can be according to the customer's size and cooperate with the transfer of the customer's expanding factory. The material of storehouse board adopts stainless steel material and steel plate baking paint material, the structure is firm, waterproof, beautiful. The horizontal diffusion vertical heat exchange circulatory system with centrifugal air supply can avoid any dead angle and make the indoor temperature and humidity distribution uniform. The IPC-500 controller can be connected with the computer by the RS-232 interface. The user can design the program on the computer, collect the test data and record, execute the calling program, remote control machine switch machine and other functions. When abnormal condition occurs, the controller screen shows the fault in time, cuts off the power switch, and provides the troubleshooting method. The refrigerating machine uses imported compressor from Europe and America, and environmental protection refrigerant. The refrigeration system is designed with binary low temperature loop system, and different compressors are used in different temperature regions to increase the service life of the equipment.
