225 Liters Test Chamber Referring Picture:

Appearance Didplay:

No.	Name	Explanation
1	Observation window	For the customer to observe the status of the object which is being tested
2	Test area	Area for putting the test object
3	Controlling table	Interface for operating the machine
4	Right side of the machine	Build-in power device
5	Door handle	For fixing and connecting the door and machine

Work principle:

1. The controlling system for adjusting temperature and humidity evenly controls SSR through PID. It makes the heating and moisture content equal the loss of heating and moisture

2. The dry and wet balls are used for measuring temperature signal by comparing the A/D conversion input controller CPU and RAN, and input to I/O board. The I/O board gives commands and instructions to operate air circulation system and cooling and freezing system, meanwhile, PID controls SSR, or heats or humidifies SSR for operation in order to make the hot and wet content deliver to the test box evenly through air circulation system, and finally achieve the purpose of adjusting the temperature and humidity evenly
