Product Details  There are Three types of air leakage systems available mainly: Manometer Air Tester hand held Air Leakage Testing Mach  When Sealing is done then we have to check if there is leakage in the sealing or welding connection or in pole post brazing. This can be done with the help of Air leakage Testing Machine. This system functions on the principle to pressurize cell at certain air/inert gas pressure and this pressure is holded for certain period, if drops below required pressure setting then it is made certain that this cell is leak. This can be done by individual cell one by one or alternative cell i.e. cell no. 1,3,5 then 2,4,6. Rate of Pressure drop also determine extant of leakage.
