Matters needing attention when using constant temperature and humidity testing machine

1. The machine needs pure water to add humidity water.

2. When the machine's high temperature exceeds 85 degrees, please remove the gauze to prevent the gauze from turning yellow.

3. The gauze is removed and cleaned once a month, and one piece is replaced every quarter. The gauze cannot be used after it has turned yellow to avoid inaccurate equipment humidity.

4. When the equipment is running at low temperature, please do not open the door at will, so as to prevent air from entering the chamber, the chamber will freeze quickly, and freezing will have a certain impact on the heating tube and evaporator in the chamber.

5. When the equipment is running at a high temperature, please do not open the door at will to prevent the hot air from flying out and burns. If it must be opened, move backward along the door of the test chamber.

6. The equipment must not be operated at high temperature (above 120 degrees) for a long time. There are refrigerated parts under the cabinet, and the mechanical refrigerating medium will evaporate during long-term operation at high temperatures, and the requirements may not be met during low-temperature tests. If there is a high temperature experiment requirement, a high temperature chamber will be better.

7. When replacing the new gauze, the gauze must be moistened as a whole, and then hung on the humidity probe at the bottom of the test chamber. The above is a temperature probe. Make sure not to make a mistake, so as not to cause the temperature of the test chamber to be incorrect.

8. Before each experiment, please confirm whether there is water in the water tank (just compare the bottom water level scale of the test chamber to see if the water level is normal), so as to avoid the machine water shortage alarm affecting the test.

9. The equipment should be about 60cm away from the wall to avoid poor heat dissipation and slow cooling of the machine.

10. The water circuit of the constant temperature and humidity testing machine should be cleaned once a month, and the corresponding valve should be opened to discharge the pure water tested before.
