For the smart watch IPX7 waterproof tester, compressed air can be used as the airtight waterproof tester for the test medium. The instrument only needs to inflate, hold, test and exhaust four stages to complete the IPX7 waterproof test of a smart watch. At present, most smart watch manufacturers use Xili's waterproof tester. This waterproof tester can not only detect the IPX7 waterproof level, but also apply to a series of tests such as IPX6 and IPX5.
The following picture shows the IPX7 waterproof test site of a company's smart watch.
