Customers familiar with high-low temperature humidity test chambers know that the equipment is equipped with observation windows, allowing them to monitor the progress and changes during testing. However, some customers may notice water mist forming during the test. Does this mist affect the test? What causes it?

First, let’s explain why water mist appears in high-low temperature humidity test chambers. Since the equipment is designed for humidity testing, it includes a humidification system. If the humidity requirement is below 50%, the humidity level is not high enough, so water mist usually does not form. However, if the humidity exceeds 50%, especially in high-humidity tests between 50% and 80%, water mist is a normal occurrence. This is similar to how a household humidifier works, so there’s no need for concern in such cases.

As for whether the water mist affects the test results, it depends on whether the equipment meets the testing requirements. Modern chambers are typically made of stainless steel, such as 304 stainless steel mirror panels, which offer excellent heat and corrosion resistance. Therefore, the impact of water mist during testing is minimal.

During testing, various phenomena may occur in high-low temperature humidity test chambers, but some are normal and usually require no intervention. If you encounter any doubts during operation, you can consult the manufacturer’s technical team to determine whether it’s a normal occurrence and whether any action is needed.
