Series Mark II Molded Plastic Air Velocity Meter

Brand: Dwyer Instruments, LLC

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.

Scales are lithograph printed on aluminum and epoxy coated.

For stationary applications, the Mark II air velocity meters can be easily mounted on any vertical surface with the two screws provided. A built in spirit level simplifies leveling.

Just fill the reservoir, adjust fluid level to zero, connect the Pitot tube, and it is ready for operation. For portable applications, the Model A-612 portable stand is available for Models 27 and 28.

A molded plastic swing-out stand and leveling screw for user installation are provided with the Model 40-1-AV which also features rapid shutoff tubing connectors and built-in over pressure traps.

Additional standard accessories include plastic connection tubing, mounting screws, 3/4 oz. bottle of indicating fluid and instructions. Metric ranges are also available.
