Dwyer® Mark II Series Manometer, Manual Static Pressure Gauge

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. Included with each Mark II manometer are 2 tubing connectors for 1/8 in pipe or sheet metal ducts, 2 mounting screws, 1 oz bottle of indicating fluid, red and green pointer flags and complete instructions. The model 25 also includes 8 ft of flexible double column plastic tubing. Portable operation of the model 25 is made possible by the use of the optional A-612 portable stand. A short piece of tubing can be slipped over the model 25 pressure connections to contain the gage fluid in transit.
