Direct Display Temperature & Humidity Chamber
1. Function provided for high temperature, low temperature andconstant temperature & humidity
2. All heat-up, pull-down, humidifying & de-humidifying are independant, high efficient,low defective and minimized costs.
3. Build-in controller, P.I.D. auto control makes temperature and humidity more effective.
4. Standard deviation point for temperature and humidity can be modified from the program.
5. Self-diagnostic capability when sensor rod defected.

control characteristics:
1. High temperature, low temperature and constant temperature & humidify can be independantly used to conform to different testing requirements.
2. Full-function trouble display including overheat, low water-level, test over and compressor overload…etc.
3. Precise timer and time accumulator make operator aware of his test time.
4. Includes P.I.D. value, lock-up, inspection sensor, rod, alarm for upper and lower level, build in micro-computer controller.
