本機在測定防水材料其耐水能力，其檢測方式依測定標準可分為定壓法及漏水法等。本機使用精密壓力轉換器感應水壓，并以電子數字LED顯示抗壓值，精密度高，并自動保留最高抗力值：單一扳手控制，簡單好用，推進器具有自動安全空檔設定：壓力設定自動持壓、自動計時、時間到自動停止：針對不同材料，加壓速度可自由設定，試驗完成全帶回位，既省試驗時間：試件固定采用壓柄式操作，省力動作快。
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 .
