Instrument use:
     The walk-in test box is one of the important testing equipment in the product development and testing stage. It is mainly used to test the product's tolerance to the external environment and long-term exposure to the natural environment, thereby detecting product defects. Optimize and detect the use environment and service life of the product. It is often used in the heat and cold resistance test of the defense industry, aerospace industry, automated components, auto parts, electronic and electrical devices, plastics, chemicals, pharmaceuticals and related products.
Features:
1. The library board unit combination is adopted, and the internal volume can be enlarged at will, easy to disassemble, and can be designed according to the customer's needs and cooperate with the customer to expand the factory in the future.
2. Using SUS#304 stainless steel plate and color steel plate, the structure is firm, easy to fold, simple structure, waterproof and beautiful.
3. The ceiling blowing type is adopted to reduce the influence of the wind speed in the test room on the sample, and at the same time, it can meet the requirements of low wind speed and high uniformity.
4. The spacious and bright large windows are equipped with high-brightness indoor explosion-proof fluorescent lamps, allowing users to observe the conditions in the test chamber during the period of time.
5. The refrigeration system uses compressors imported from Europe and the United States, environmentally-friendly refrigerants, power supplies for the product under test, and machine safety protection, devices, all adopt a continuous control design method.
6. All-round safety protection device and power failure memory ensure the safety of the machine itself and the user. Comprehensive protection device, when an abnormality occurs, the controller screen will automatically display the fault status instantly, cut off the power switch, and provide troubleshooting methods.
