Working principle:
Easy To Operating Temperature Humidity Chamber (heating and cooling) and humidification is composed of two parts. Through installation in box within top Department of rotating fan, will air row into box achieved gas cycle, and balance box within of temperature, and humidity, by box built-in of temperature, and humidity sensor collection of data, biography to temperature, and humidity controller (micro information processing device) for edit processing, issued thermostat adjustable wet instruction, through air heating unit, and condensation tube and sink within heating evaporation unit of common completed.
