Air-based pressure leak detector in various pressure levels specially adapted to the requirements of double-walled plastic pipes.
The DLR-P .. CV is equipped with a check valve in the connection line. This avoids that gas may flow towards the leak detector (zone reduction). Therefore, the leak detector DLR-P .. CV can also be used for pipes that have a low permeation.
For pipes conveying explosive liquids, monitoring with air is cheaper in the long term than with nitrogen.
