This video introduce YONGUCase aluminum waterproof enclosure making a waterproof test in high pressure and underwater. Many YONGU R&D waterproof enclosure will be tested by this pressure vessel. After test and revise, we will find a specialized certification body for waterproof certification testing.

Put the aluminum enclosure in a pressure vessel, fill it with water, cover the container, and tighten it with a screwdriver.

 

Fill the interior with air, increasing the air pressure. Set pressure at 30N/m²

Then, the waterproof box sits in the pressure vessel for 3 hours. It has been tested for a long time before, so this time it is just a test video to show the waterproof ability.

The waterproof test paper will change color to be red as long as it encounters water, which means the test is successful.
