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
