Mark II Model 40-1 Dwyer Manometer Range .1-0-1.0 Inches w.c
Mark II Manometers are economically priced, compact and available in both stationary and portable configurations. The portable stand is a standard feature on Model 40. 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. Greater protection is provided by float operated overflow traps in the Model 40. Scales are lithograph printed on aluminum and epoxy coated.
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.
