Tablet computers have become a very common mobile device in daily life, but no matter which electronic device it is, there are always accidents of water intrusion. Therefore, waterproof tablet computers have attracted people's attention. The focus is to achieve IP67 waterproof level and carry out IPWaterproof test。

With Huawei Honor’s latest“WaterPlay”With the release of waterproof tablets, the waterproof function of tablets is no longer a dream, and the equipment for testing waterproofing of tablets is air tightnessWaterproof tester。

IP67 waterproof testThe meaning is that strong water spraying on the case from any direction will not cause harmful effects, and short-term immersion at normal temperatures and pressures will not cause harmful effects when the tablet is temporarily immersed in 1M deep water.

The traditional water immersion test method is not feasible for waterproof testing of tablet computers, because once water enters, the tablet computer will be damaged, so the new test method is used.Air tightness detectorTesting tablets for water resistance is the most reliable method

new typeAir tightness detectorHow to test the IP67 waterproof test of tablet computers?

First, we can make a relatively sealed test tool based on the shape of the flat computer, then put the tablet computer into the test tool, connect the air source, and then go through the three stages of inflation, stabilization, and detection. The waterproof tester will calculate the leakage value. Based on the leakage, the IP67X waterproof level of the tablet computer can be determined. It can also be used for IP68 waterproof level testing. The difference lies in the size of the leakage value and the test pressure.

TabletWaterproof testerThe main technical parameters are as follows
