Molded Plastic Manometers3% Accuracy for Stationary and Portable Applications at Minimum Cost
Dwyer Mark II series moldedmanometers are of the inclined andinclined-vertical types. The curvedinclined-vertical tube of the Model 25gage provides higher ranges with moreeasily read increments at low readings.The Model 25 is excellent for generalpurpose work. The Model 40 inclined gageprovides linear calibration andexcellent resolution throughout itsrange. The Model 40 is ideally suitedfor air velocity and air filter gageapplications. Both gage types arecapable of pressure measurements aboveand below atmospheric as well asdifferential pressure measurements.
