Principle
Humidity chamber realizes low temperature control through cascade refrigeration system. It consists of high temperature part and low temperature part, which are connected by evaporative condenser. The heating system uses high power resistance wire to achieve rapid heating up. The temperature and humidity system is divided into humidification and dehumidification subsystems. The humidification adopts steam humidification method, and the dehumidification mainly adopts mechanical refrigeration and dehumidification. The Sensor system uses platinum resistance and Thermocouple measurement temperature. The solid state electronic Sensor humidity measurement.
Applications
Plastics, electronics, food, clothing, vehicles, metals, chemicals, building materials

Steps
1. Set up program catalog management, establish test names and program data
2. Select the operation mode: fixed value/program/link
3. Set the reservation start function
4. Lock the start-stop function conditions to prevent misoperation
5. Configure external protection devices
6. Online control with PC via RS-232 interface
7. Switch between Chinese and English to display subtitles
8. Manually add water 20L each time
9. Place the product on the test rack to ensure that the load-bearing capacity does not exceed 20 kg
Notice
• Power supply voltage must be 220V AC (+/- 10%), protective grounding resistance ≤ 4Ω
• Do not use knife switches or power sockets, must use air switches (40A)
• The resistivity of humidification water needs to be ≥ 500MΩ
• The load-bearing capacity of the product rack does not exceed 20kg
• Note that safety devices include air burn prevention, high voltage protection, overheating protection, overcurrent protection, etc
• The frequency needs to be kept at 50 +/- 0.5Hz
• Power is about 3.5KW, ensure power matching
