The Wöhler DP 600 checks the tightness of exhaust ducts and chimneys. The menu enables the user to select between the different installation types. The Wöhler DP 600 regulates automatically the pressure which is necessary for the flue gas systems type P1 (exhaust ducts), H1 (combined heat and power plants, exhaust ducts with high pressure), N1 and N2 (chimneys) and determines the leakage rate automatically.
It also disposes of a variable mode which allows the user to select the test pressure and the leakage rate. This way, tightness tests of ventilation systems or flue gas systems type P2 or H2 are also possible. A thermal fast printer can print all results.

New: Also suitable for the confirmation of a sufficient combustion air supply according to DVGW 625 („simple procedure“ and „detailed procedure“) with the necessary differential pressure test (4 Pa test). No auxiliary measuring instrument will be necessary.
The Wöhler DP 600 simulates the combustion air inlet of a fireplace. After the user has entered the capacity of the fireplace, the Wöhler DP 600 will produce automatically the corresponding volume flow which passes through the chimney and will  register the pressure progression in the room.
