There are two sets of filter bottles at the water inlet of the test chamber. We soak them in salt water for 24 hours every year, and then rinse them with clean water.
If you plan not to use this test chamber for a long time, please remove the residual moisture in the working room and then dry it. Finally, remove the dust from the inside of the equipment and the cabinet, and then close the plastic cover. However, it should be noted that the equipment needs to be energized regularly during power outages, otherwise problems may occur when the test chamber is used again.
