What should I do if the temperature of the constant temperature and humidity test chamber does not reach the set value?

When the temperature of the constant temperature and humidity test chamber does not reach the set value, pay attention to the change of temperature.

1. The temperature drops very slowly. Two aspects need to be checked. One aspect is whether the studio has been dried before the low temperature test. The studio must be dried before the test, and then the test sample is put in the test. Another aspect is whether there are too many test samples in the working room, causing the wind in the working room to not be fully circulated.

Solution: Consider whether it is a fault in the refrigeration system, so that professionals should be asked for maintenance (Huanrui test).

2. constant temperature and humidity test chamber If the temperature has a tendency to rise after reaching a certain value, you can first check whether it is caused by the use environment of the constant temperature and humidity test chamber, the ambient temperature where the constant temperature and humidity test chamber is placed and where it is placed (the distance between the back of the chamber and the wall) ) Whether it meets the requirements, etc. (There are provisions in the equipment operation instructions).

Solution: the use environment of the constant temperature and humidity test chamber equipment is not good. The  constant temperature and humidity test chamber and placement position (the distance between the back of the chamber and the wall) of the equipment must meet the requirements.
