Desktop cold and hot shock box can not reach the low temperature how is it? How to solve?

Desktop cold and hot shock box can not reach the low temperature how is it? How to solve? During the operation, the user found that the desktop cold heat shock box sometimes encounters the situation that the low temperature cannot reach. For this reason, Haida engineers made the following answers based on this phenomenon:

First of all, to understand the structure of the desktop heat shock box, the studio is generally divided into three separate spaces:

1 , the refrigeration room

2 , high temperature,

3. The intermediate space is the item placing area. Under the condition of high and low temperature environmental changes, the parameters and performance of the test product after the temperature and impact change of the high and low temperature test are tested, and the adaptability of the test is used.

When the table-type cold and hot shock box can not reach the test index of low temperature exclusion method:

1. Observe the change of temperature, which is the temperature drop is very slow, or the temperature has a tendency to rebound after the temperature reaches a certain value.

2 , the first phenomenon, then check whether to do the low temperature test before the studio drying, drying and then put the test sample to do the test, the test sample is placed too much, the wind can not be fully recycled, such as the above two reasons to exclude After that, it should be considered whether there is a failure in the refrigeration system, and professionals must be inspected and repaired.

3. The second phenomenon is caused by the poor use environment of the machine. The location of the environment should meet the requirements.

Desktop cold and hot shock box can not reach the low temperature how is it? How to solve? Through the above analysis and exclusion, users can eliminate one by one according to the above method when they encounter such problems.
