Dwyer Instruments - Series Mark II: Mark II 40-1 Molded Plastic Manometer

   Dwyer Mark II Series Molded Manometers are of the inclined and inclined-vertical types. The Model 40 inclined gage provides linear calibration and excellent resolution throughout its range. Also, it is ideally suited for Air Velocity and Air Filter Gage Applications. 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. 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.

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 40 contains two 4-1/2 foot 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.

Specifications
Accuracy: 3% full scale.
Maximum Working Temperature: 130F (54C).
Maximum Internal Working Pressure: 15 psi (100 kPa).
Scale Length: Approx. 8-1/4" (21 cm).

Accurate Pressure Measurement

Engineered for low differential air or gas pressure, the Mark II 40-1 Series manometer guarantees reliable readings from 01 inch water column. Its inclined-vertical scale enhances sensitivity for small pressure changes, making it ideal for industrial monitoring and control tasks.


Robust Construction and Safety Features

The clear acrylic body, injection molded for durability, houses integral overflow chambers for overpressure protection. Its neoprene seal caps ensure tight connections, while the zero-adjust knob offers easy baseline calibration for repeated accurate measurements.


Convenient Mounting and Usage

This manometer can be wall or surface mounted, allowing flexible installation in labs or industrial spaces. Lightweight at approximately 170 grams and equipped with portable features, it is suited for stationary setups or transport between test sites.
