2. The inner liner is made of SUS304 mirror stainless steel plate;
3. High density glass fiber cotton is selected as the insulation material, with a thickness of 100mm for the insulation layer;
4. The temperature and humidity circulation system adopts a specially designed low-noise long axis fan motor with stainless steel multi blade impellers that are resistant to high and low temperatures, to achieve strong convection and vertical diffusion circulation;
5. A double-layer high-temperature resistant high tensile sealing strip is used between the door and the box to ensure the sealing of the testing area;
6. Adopting non reactive door handles makes operation easier;
7. The bottom of the machine adopts high-quality fixed PU movable wheels;
8. The observation window adopts multi-layer insulated tempered glass, and the inner side is coated with laminated conductive film for heating and defrosting (clearly observe the test process);
9. The test hole (on the left side of the machine) can be used for external testing power or signal lines (the aperture or number of holes needs to be increased and indicated);

3、 Control system:
1. Adopt a "7.0-inch" high-precision digital temperature and humidity control instrument, P.I.D high-precision control, to prevent long-term unstable operation;

2. Humidity is controlled through intuitive display, eliminating the shortcomings of the original temperature and humidity comparison;
3. Accuracy: ± 0.1 ℃ (display range);
4. Resolution: ± 0.1 ℃;
5. Temperature sensor: PT100 platinum resistance tester;
6. Control mode: Thermal balance temperature regulation mode;
7. Electrical control: The main components of electrical control adopt imported "Schneider" and "Chint" components to better control temperature;
8. The return air outlet of this test chamber is equipped with an automatic defrosting device (so that the water vapor generated during the test will not accumulate on the refrigeration evaporator and cause ice blockage);

4、 Heating system:
1. Adopting far-infrared nickel alloy high-speed heating electric heater;
2. High temperature independent system, does not affect low temperature test and wet heat test;
3. The output power of temperature and humidity control is calculated by a microcomputer to achieve high-precision and high-efficiency electricity efficiency;

5、 Humidification system:
1. Built in boiler steam humidifier;
2. Equipped with automatic water level compensation and water shortage alarm system;
3. Far infrared stainless steel high-speed heating electric heating tube;
4. The humidity control adopts P.I.D+S.S.R, and the system coordinates control with the same channel;

6、 Refrigeration system:
1. Compressor: Fully enclosed original French Taikang unit;
2. Cooling method: single (double) mechanism cooling (air-cooled type);
3. Condensation method: forced air cooling;
4. Refrigerants: R404A, R23 (environmentally friendly);
5. All system pipelines undergo a 48 hour leak detection test with ventilation and pressurization;

7、 Protection system:
1. Fan overheating protection;
2. Overall equipment under phase/reverse phase protection;
3. Overload protection for refrigeration system;
4. Refrigeration system overpressure protection;

8、 Equipment usage conditions:
1. Environmental temperature: 5 ℃ to+28 ℃ (average temperature within 24 hours ≤ 28 ℃)
2. Environmental humidity: ≤ 85% R.H
3. The operating environment requires good indoor ventilation, and no objects should be placed 80 centimeters in front, back, left, right, or right of the machine;

9、 Compliant with standards: strictly follow GB/T10592－2008、GB/T10586－2006、GB/T2423.1-2008、GB/T2423.2-2008、GB/T2423.3-2006 Design and manufacture according to relevant standards;
