How to master the size of the constant temperature and humidity box? Of course, this must be "tailor-made", and the size of the constant temperature and humidity box can be selected according to the size of the test product, so as to ensure reliability. And the power plug when purchasing It is also a content that cannot be ignored. Generally speaking, paying attention to the stability of the stability, it is necessary to choose more than 3-phase power plugs. If there are special high requirements, even 4-phase power plugs should be selected.

Should the constant temperature and humidity box be air-cooled or water-cooled? Generally speaking, the test can be achieved by using air-cooling, otherwise water cooling can be used in large constant temperature and humidity chambers. In addition, the test environment of the constant temperature and humidity box is also worthy of attention. It is necessary to ensure the reliability and perfection of the maintenance and alarm measures of the environmental test equipment, the safety chain installation, etc., to ensure the safety and reliability of the entire test.

When using the constant temperature and humidity box, you must first observe the change in temperature. If the temperature drops slowly, you need to check the following points. Whether the studio has been blown dry before the low temperature test, and the studio must be dried before the test. Then put the test sample into the test; whether the test sample in the working room is placed too much, so that the wind in the working room cannot be fully circulated, after solving the above reasons, it is necessary to consider whether it is a problem with the refrigeration system, and the refrigeration system The maintenance of the system needs to be operated by the professional personnel of the manufacturer.

If the temperature has a tendency to rise after reaching the corresponding data, you can first check whether it is caused by the use environment of the constant temperature and humidity test box, and whether the ambient temperature of the equipment and the position (the distance between the back of the box and the wall) are not meet requirements etc.
