Dwyer Manometer

Mark II Moulded Manometers


Dwyer® Mark II series molded manometers are of the inclined and inclined-vertical types. The curved inclined-vertical tube of the Model 25 gage provides higher ranges with more easily read increments at low readings. The Model 25 is excellent for general purpose work. The Model 40 inclined gage provides linear calibration and excellent resolution throughout its range. The Model 40 is ideally suited for air velocity and air filter gage applications. Both gage types are capable of pressure measurements above and below atmospheric as well as differential pressure measurements.


Accuracy: ±3% full scale.
Maximum Working Temperature: Inclined/Vertical Models: 140°F (60°C); Inclined Models: 130°F (54°C).
Maximum Internal Working Pressure: Inclined/Vertical Models: 10 psi (70 kPa); Inclined Models: 15 psi (100 kPa).
Scale Length: Inclined Models: Approx. 8-1/4" (21 cm)
