This tester tests samples by lifting a certain volume of water, at a speed of 1cm/second; until 3 drops of water appeared, stop the motor lifting; the height of the water in mm is recorded as the test result.
Test Methods
Leakage measurement to raise water to the certain height at specified speed, to measure the water volume (ml) leaked during certain time.
Water pressure raise water at speed of 1cm/sec, until three locations of surface of specimen get water penetration, the height of water is recorded
Fixed water pressure raise water position to certain height at speed of 1cm/sec. Then pause, immediately record the time (sec) when three locations of surface of specimen get water-penetration.
