本机在测定防水材料其耐水能力，其检测方式依测定标准可分为定压法及漏水法等。本机使用精密压力转换器感应水压，并以电子数字LED显示抗压值，精密度高，并自动保留最高抗力值：单一扳手控制，简单好用，推进器具有自动安全空档设定：压力设定自动持压、自动计时、时间到自动停止：针对不同材料，加压速度可自由设定，试验完成全带回位，既省试验时间：试件固定采用压柄式操作，省力动作快。
The Hydrostatic head tester is used for determination of the resistance of waterproof cloth synthetic leather and leather to water penetration ,either by the static test method or dynamic test method .Use accuracy pressure transducer to measure water pressure and convert to LED display; it can also reserve the peak value .operation is easy only by lever and the safety setting is also pervaded .After the test has been material of specimen ,the pressure speed is adjustable ,operation ill be automatically stopped when the preset time is reached /According to the different material of specimen ,the pressure speed is adjustable ,op e ration will beutomatically returned by full speed after test is stopped to save the test time .the specimen is clamped by a lever ,which is more easily and quickly .
