Main features:

1. The material of the inner box is imported SUS304 # mirror stainless steel, and the outer box is made of steel plate with baking paint. The box body is processed and formed by CNC machine tools, with a beautiful and generous shape.
2. The insulation material adopts high-strength PU foam and high-density glass fiber cotton, which can avoid unnecessary energy loss.
3. Large window glass design for all-round viewing angle; Hollow plated electric heating film anti condensation design, built-in lighting, convenient for real-time observation of the test product status during testing.
4. Large LCD display screen, easy to operate and program editing.
5. It has PID automatic calculation function and fault message display.
6. Equipped with RS-232 communication interface, optional recorder, strong rechargeable.
7. It has timing contacts and can be used for dynamic and measurement tests.
8. It has multiple security protections and power outage memory functions for the entire system.
9. The freezer adopts a French imported ironclad Warrior compressor and uses environmentally friendly refrigerants (R134a, R404a, R23)
10. The refrigeration system adopts a unit or binary low-temperature circuit system design.
11. By utilizing a multi wing air supply fan for powerful air circulation, any dead corners can be avoided, resulting in even temperature and humidity distribution within the testing area.
12. The air circulation adopts a side blowing air return design, with wind pressure and speed that meet the test standards, and can quickly stabilize the temperature and humidity at the moment of opening the door.
13. Fully independent heating, cooling, humidification, and dehumidification systems can improve efficiency, reduce testing costs, extend lifespan, and lower failure rates.
