Principle
The refrigeration system adopts cascade refrigeration, which is composed of high temperature part and low temperature part, and is connected by evaporative condenser. The heating system is composed of high power resistance wire, which realizes rapid heating up. The temperature and humidity system is divided into two subsystems of humidification and dehumidification. The humidification adopts steam humidification method, and the dehumidification adopts mechanical refrigeration dehumidification and drying dehumidification. The Sensor system adopts platinum resistance and Thermocouple temperature sensor, and solid state electronic humidity sensor for accurate measurement.
Applications
Plastics, electronics, food, clothing, vehicles, metals, chemicals, building materials

Steps
1. Turn on the power supply, ensure that the voltage is 220V AC (+/- 10%), and the grounding resistance is ≤ 4Ω.
2. Manually add water to the humidification system, 20L each time
3. Set up the test program through a 5.7-inch LCD color LCD display
4. Select the operation mode: fixed value/program/link
5. Temperature range 25~ 100 ℃ and Humidity range 20~ 98% R.H
6. Start the device running
7. Monitor actual operation Linear dispersion
8. Turn off the device after the test is completed
Notice
• Power supply voltage must be 220V AC (+/- 10%)
• Protective ground wire must be used, ground resistance ≤ 4Ω
• The resistivity of humidification water needs to be ≥ 500MΩ
• The weight of the product rack shall not exceed 20 kg
• Do not use knife switches or power sockets, must use air switches (40A)
• Pay attention to the safety devices of the equipment: air burn prevention, high voltage protection, overheating protection, overcurrent protection, Pottery and porcelain E-16 fast fuse, no fuse overload protection
• Pay attention to locking the start-stop function during operation to prevent accidental touch from affecting the experimental results
