wyer Instruments - Series Mark II: Mark II 26 Molded Plastic Manometer

Stand Sold Seperately (A-612)

Dwyer Mark II series 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. Capable of pressure measurements above and below atmospheric as well as differential pressure measurements.

Construction
Mark II manometers are economically priced, compact and available in both stationary and portable configurations, optional A-612 stand for Model 25. Construction is simple with virtually indestructible molded white styrene-acrylonitrile housing, indicating tube and fluid wells, molded ABS knobs and zero adjust plunger, shock mounted glass level vial and leak proof O ring seals. Moderate overpressures are accommodated by an overflow tank. Scales are lithograph printed on aluminum and epoxy coated.

Installation
Mark II manometers can be mounted on any vertical surface with the two mounting screws provided. A built-in spirit level simplifies leveling before mounting screws are tightened. Simply fill the reservoir, adjust fluid level to zero, connect the tubing, and the gage is ready for operation.

Accessories
Included with each Mark II manometer are two tubing connectors for 1/8" pipe or sheet metal ducts, two mounting screws, 3/4 ounce bottle of indicating fluid, red and green pointer flags and complete instructions. The Model 25 also includes 8 feet of flexible double column plastic tubing. Portable operation is made possible by the use of the optional A-612 portable stand. A short piece of tubing can be slipped over the pressure connections to contain the gage oil in transit.

Specifications
Accuracy: 3% full scale.
Maximum Working Temperature: 140F (60C).
Maximum Internal Working Pressure: 10 psi (70 kPa).
