Principle
The humidity chamber realizes low temperature control through a 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 adopts mechanical refrigeration dehumidification or drying dehumidification method. The Sensor system uses platinum resistance and Thermocouple for temperature measurement, and the solid state electronic Sensor for humidity measurement.
Applications
Plastics, electronics, food, clothing, vehicles, metals, chemicals, building materials

Steps
1. Set up program catalog management, create or change test names and program data
2. Select the operation mode: three operation modes such as fixed value/program/connection
3. Set the reservation start function
4. Lock the operating conditions to prevent accidental touch
5. Configure the humidification system box water supply, manually add 20L of water each time
6. Place the product on the test rack (the weight of the product rack is within 20 kg)
7. Start testing and monitor actual operation Linear dispersion
Notice
• Power supply voltage must be 220V AC (+/- 10%), protective ground wire, ground resistance ≤ 4Ω
• Do not use knife switches or power sockets, use air switches (40A)
• The resistivity of humidification water needs to be ≥ 500MΩ
• The weight of the product rack shall not exceed 20 kg
• Note that safety devices include air burn prevention, high voltage protection, overheating protection, overcurrent protection, Pottery and porcelain E-16 fast fuse, no fuse overload protection
• After power failure, you need to select the reset timing and restart mode: BREAK (interrupt), COLD (cold engine start), HOT (hot engine start)
