T: 219-879-8000 | F: 219-872-9057 | info@dwyermail.com 800-872-9141 SERIES MARK II | MOLDED PLASTIC MANOMETERS FEATURES/BENEFITS • Broad ranging in easy to read calibrated increments • Gages ideally suited for general measurements and specific air applications • Compact, stationary or portable device, make it a simple to use tool for pressure measurement in OEM or user applications APPLICATIONS • Paint booths • Air velocity measurement • Air filter gage DESCRIPTION Series MARK II 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.
