Water Penetration Tester tests water penetration of waterproof material by a raising cup. According to using pressing force and environment difference, there are high pressure(0~40000mm/aq) tester, low pressure(0~2000mm/aq) tester and portable type water penetration tester. The testing principle of these three testers is to pressurize by constant pressing force until over three globs come out and stop recording the value of water colum high pressure. Another test method is to pressurize by a constant pressing force in a definite period, and watch if there is glob comes out to determine the qualification.
