A sailboat company in Fujian uses Hirays' waterproof sealing testing equipment to detect the waterproofing and sealing of sailboat batteries:

Sailboat batteries are relatively large, and they are used in the water for a long time, so their detection is relatively difficult, but for Haris, it can still be done, because the accuracy of our testing equipment can be as high as 0.1PA, which is very suitable for sealing and waterproof testing in this area.As the country vigorously promotes hybrid vehicles, it is also necessary to test the sealing of car batteries because water may enter the battery. Hirays leak detection equipment is also very suitable for testing.
