Dwyer's Molded Plastic Manometers Offer 3% Accuracy for Stationary and Portable Applications at Minimum Cost!
Dwyer Mark II series molded manometers are of the inclined and inclined-vertical types. The curved inclined-vertical tube of the Model 25 gauge provides higher ranges with more easily read increments at low readings. The Model 25 is excellent for general purpose work.
The Model 40 inclined gauge provides linear calibration and excellent resolution through out its range. The Model 40 is ideally suited for air velocity and air filter gauge applications.
Both gauge types are capable of pressure measurements above and below atmospheric as well as differential pressure measurements.
