Leak Integrity
We recommend to check leak tightness of all ports and connections of the plumbing with a helium
leak detector.
Pressure Drop Test
If a leak check at high pressure is intended then check for the highest allowable pressure for all
parts involved. Example: If a pressure based leak check at 5 bar (g) is done you will damage a
pressure transducer in the line if it is limited to 3.5 bar (g). In this case the pressure transducer (or
whatever component is affected) must be removed or protected by a suitable valve.
Dimensions

and USB Units.
