Principle
Humidity chamber works together through the refrigeration system, heating system and temperature and humidity system to achieve accurate environment simulation. The refrigeration system adopts cascade refrigeration, which consists of two parts of high temperature and low temperature. It is connected by evaporative condenser to absorb heat separately to obtain cold capacity. The heating system is composed of high power resistance wire, which provides rapid heating capacity. The temperature and humidity system includes humidification and dehumidification subsystem. The humidification adopts steam humidification method. The dehumidification adopts mechanical refrigeration dehumidification or drying dehumidification method to ensure the sensitivity and accuracy of temperature and humidity control.
Applications
Plastics, electronics, food, clothing, vehicles, metals, chemicals, building materials

Steps
1. Set the test program: use the programmable controller to set parameters such as temperature, humidity, and time
2. Start the device: Select the cold or hot engine start mode and start running
3. Monitoring operation: real-time observation of temperature and humidity Linear dispersion and status through LCD display
4. Handling abnormalities: If there is a fault alarm, deal with it accordingly according to the prompts
5. End the test: automatically stop or manually stop running after the program is completed
