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 the electrical control system use imported "Schneider" and "Merlin Gerin" 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. The high-temperature system is completely independent and does not affect the low-temperature test or 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， Coordinate and control the system 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;
6. The heating and cooling systems are completely independent;
7. Internal spiral refrigerant copper tube;
8. Slope evaporator;
9. The dry filter, refrigerant flow window, repair valve, oil separator, solenoid valve, and storage tank are all imported original parts;
10. Dehumidification system: using evaporator coil dew point temperature laminar contact dehumidification method;
11. Start R404A when cooling down R23， Only start R404A during dehumidification (energy-saving and consumption reducing);

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;
5. Overall equipment timing;
6. Overheating of the water pump and overcurrent protection;
7. Other protections include leakage, water shortage, operation indication, automatic shutdown after fault alarm, etc;

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: Designed and manufactured strictly in accordance with relevant standards such as GB/T10592-2008, GB/T10586-2006, GB/T2423.1-2008, GB/T2423.2-2008, GB/T2423.3-2006, etc;
