In both Chinese and English display optional, interface clear, humanized operation.

4. Working principle

Constant temperature and humidity incubator is working by feeling the actual temperature and humidity, then transfer into electrical signals through temperature and humidity sensor , heater or refrigeration compressor working under the microcomputer control ,so as to achieve the required temperature; control the humidifier to reach the humidity as required.

5. Run Preparation

Before the first operation of this machine, please do according to the following procedure:

1. Remove the shelf and other accessories inside equipment
2. Use alcohol soaked sponge to wipe disinfection cabinet wall, then using a dry gauze with alcohol wipe to clean
3. Put the shelf according to the experimental requirements inside equipment.
4. Before using ,water tank should be placed on the top of the equipment, then insert pipe to back water inlet and weir (refer to the parts diagram), and placed water basin for use under the overflow pipe outlet.
5. Give enough water into the water tank.
6. Before the equipment is energized, the air in the rubber tube should be discharged first. The steps are as follows: Connect the water tank with the rubber tube 1, the ball pump and the rubber tube 2, and unscrew the water supply switch of the water tank. At this time, the air and water in the pipe will flow out together. If not, squeeze the ball pump until the air and water in the pipe flow out smoothly, and the other port of the rubber tube 2 can be connected to the water inlet interface of the equipment. Note: If the air is not effectively discharged, water may not enter the tank, resulting in abnormal humidification.
