Pressure, leak and leak rate measurement

The Dräger P7plus is ideal for testing gas and liquid gas lines all the way to waste water line and drinking water installation testing. It performs leak rate measurement at top speeds – without removing the gas meter, without determining the volume and without pressure boosting.


Testing gas, liquefied petroleum gas and water lines
The Dräger P7plus tests gas and liquefied petroleum gas lines in addition to water and waste water lines measurements. In addition to pressure measurements up to 5 bar, the Dräger P7plus test for proper pressure regulator function. The multifunction jack for peripheral devices makes the device even more variable and allows for additional applications such as pressure measurement up to 25 bar via external sensors.
