Series Mark II Molded Plastic Manometer

Brand: Dwyer Instruments, LLC

Series Mark II 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 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. 

Included with each Mark II manometer are two tubing connectors for 1/8" pipe or sheet metal ducts, two mounting screws, 1 ounce bottle of indicating fluid, red and green pointer flags and complete instructions.

The Model 25 also includes 8' 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.

The Model 40 contains two 4-1/2' lengths of clear plastic tubing, a plastic swing-out stand and leveling screw for portable operation. It also features convenient rapid shutoff pressure connections and integral overpressure safety traps.
