Works on the reverse principle of pressure testers. |
| |
Vacuum is developed by expansion of air inside the screw pump. |
| |
No External source required for creating vacuum, built in screw pump is adequate for effective and faster vacuum build-up |
| |
Force produced by difference in atmospheric pressure and reduced pressure inside the tester is balanced by calibrated weights. |
| |
Built in electric power rotation for free piston and weights. Removes operator error and fatigue. This improves accuracy. |
