The Dwyer Mark II 40-1 Molded Plastic Manometer has a range of .1-0-1.0" w.c., red oil, .826 sp. gr.
Dwyer® Mark II series molded manometersare 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 throughout 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.
