The constant temperature and humidity chamber can accurately simulate the complex natural environment of low temperature, high temperature, high temperature and humidity, low temperature and humidity, which is suitable for product reliability testing in plastics, electronics, food, clothing, vehicles, metals, chemicals, building materials and other industries.

If the constant temperature and humidity test chamber is not used for a period of time due to special circumstances, some protective measures should be taken. The specific methods are as follows:

1. When the constant temperature and humidity test chamber is not in use, the items in it should be taken out. The power plug should be unplugged, and the inside and outside should be cleaned.

2. Use paper strips between the door seal and the chamber to prevent them from adhering to each other. If it is not going to be used for a long time, apply some talcum powder on the door seal.

3. The constant temperature and humidity test chamber out of use must also be placed in a dry and ventilated place to avoid direct sunlight. The test chamber should be kept stable after the position is moved.

4. The indoor air has a certain humidity, so do not cover the test chamber with a plastic bag to prevent moisture that enters from escaping, causing corrosion of metal parts and damage to the performance of electrical components.

5. The freezing temperature of the refrigerant in the constant temperature and humidity incubator is very low, so there is no need to worry about freezing and put it at a higher temperature place.

6. Turn on the power once a month and let the compressor run normally for half an hour to one hour before turning it off.
