Functions that the equipment can achieve: Carry out temperature and humidity regulation control for both the left and right boxes. The left box should also have a spray system and a lighting system, while the right box should have a ventilation and drying system.
Sprinkler system: Equipped with multiple nozzles, the flow rate, pressure and water temperature can be adjusted and controlled. It can continuously spray for 12 hours.
Lighting system: The irradiation intensity can be adjusted and controlled. It monitors the temperature of the blackboard and is equipped with multiple bulbs.
Control system: The sprinkler system and lighting system can be controlled in sequence, and there is an overlapping working area.

Test methods and principles:
The automotive fogging test mainly employs three methods: the gloss method calculates the fogging value by measuring the change in reflectivity of the glass plate before and after condensation; the fog degree method assesses the change in transmittance; the weight method directly measures the difference in mass of the aluminum foil before and after condensation. The test typically simulates the fogging situation of vehicle lights or interior components when subjected to sudden temperature changes, with the temperature range reaching from -40℃ to 150℃, and the humidity control accuracy being ±2% RH.
