Hydrostatic Pressure Tester, Used to test water-proof or leakage of fibre, synthetic leather, wrapped paper, etc.

The test ways as below(i.e. get the average value of three operations, calculated to the first decimal):

• Leakage measurement: raise water position to 10cm. To measure the water volume(ml)leaked during certain time.
  
  
• Water pressure: raise water position at speed of 1cm/sec, the record the actual water position when three locations of surface of specimen get water penetration.
  
  
• 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.
