In our own investment we bought a new Wöhler DP 600 compactness tester.
The modern equipment performs leakage monitoring of pressurized flue gas conductors, typically at a test pressure of 200 Pa.
The test pressure value is freely selectable, so the measurement of the 1500 Pa that is about to be introduced and of the already standard 5000 Pa can be no problem. The compactness test can be ordered at any of our contact details.
