5. Humidity range: 45-70% RH;

6. Humidity accuracy: ±2% RH;

7. Light simulation system: Equipped with seven sets of lighting systems, six dedicated adjustable-height plant growth platforms with adjustable and controllable light intensity (0-800 μmol), and one set for building material aging tests with controllable intensity and sinusoidal curve simulation for daily sunlight intensity variations;

8. Light source modules: Red-blue spectrum light source, full-spectrum light source, waterproof rating: IP68;

9. Fresh air system: Built-in air circulation system with controllable wind speed (0-3 m/s) and adjustable wind direction (vertical, parallel, and multiple angles);

10. Dual-redundant independent touchscreen control systems, each with a data acquisition module. Both systems can independently control the climate environment in their zones or operate simultaneously with algorithmic cross-control to simulate complex climate conditions;

11. Users can define no less than 100 test programs, each containing 99 configuration commands. Test programs and configuration commands allow arbitrary setting of parameters such as time, jumps, loops, and cross-operation;

12. Dynamic coordinated programming control for multiple parameters (temperature, humidity, wind speed, etc.) using trigonometric functions (sinusoidal simulation), rectangular, and linear variation modes, as well as constant-value testing for related parameters;
