About Mark II Model 25 Dwyer Manometer Range 0-3 Inches WC

Mark II Model 25 Dwyer Manometer Range 0-3 Inches WC

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 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.

Below Are Other Pressure Ranges Available For Series Mark II Manometer:

Model	Range	Fluid Used
Mark II 25	0-3 in w.c.	Red oil, .826 s.g.
Mark II 26	0-7 in w.c.	Blue oil, 1.91 s.g.
Mark II 27*	0-7000 fpm	Red oil, .826 s.g.
Mark II 28*	0-10,500 fpm	Blue oil, 1.91 s.g.
Mark II MM-80	0-80 mm w.c.	Red oil, .826 s.g.
Mark II MM-180	0-180 mm w.c.	Blue oil, 1.91 s.g.
Mark II M-700PA	10-0-700 Pa	Red oil, .826 s.g.

*Requires Pitot tube at additional cost. See Air Velocity Section.

High Precision and Industrial Grade Quality

Engineered for demanding HVAC and air measurement tasks, the Mark II Model 25 offers robust construction via a clear acrylic body and a precision-molded finish. Its high accuracy, coupled with industrial-grade reliability, ensures repeatable results for professionals. The analog display utilizes a liquid meniscus, aiding precise manual readings, and its rugged build facilitates performance in various environmental conditions.

Easy Installation and Versatility

This manometer is supplied with wall or surface mounting hardware, red gauge fluid, and durable rubber tubing for versatile and convenient setup. The compact size makes it suitable for confined or challenging spaces. The scale is clearly printed on the acrylic dial, simplifying routine monitoring in HVAC systems, for air velocity checks, duct static pressure, and filter state assessments.

FAQ's of Mark II Model 25 Dwyer Manometer Range 0-3 Inches WC:

Q: How do I install the Mark II Model 25 Dwyer Manometer?

A: The manometer can be installed using the supplied mounting hardware on a wall or flat surface. Attach the provided rubber tubing between the device and the air source under measurement. Ensure the gauge fluid is filled to the recommended level and the unit is level for accurate readings.

Q: What types of media can be measured with this manometer?

A: This model is suitable for measuring the pressure of clean air and non-corrosive gases only. It is important not to use it with any liquids or corrosive substances, as these can damage the acrylic body or the gauge seals.

Q: When should I use the Mark II Model 25 manometer?

A: Use this device when you need precise measurement of low pressure differentials, such as during HVAC system balancing, checking duct or filter static pressure, or monitoring air velocity. It is ideal for maintenance routines and system diagnostics within its 0-3 Inches WC range.

Q: Where is this manometer typically utilized?

A: The Mark II Model 25 is commonly used in industrial, commercial, and institutional facilities for HVAC maintenance, laboratory applications, and air system monitoring. Its compliance with OSHA regulations makes it suitable for a wide range of workplace environments.

Q: What are the benefits of using a liquid column manometer like this model?

A: A liquid column manometer provides a simple, reliable way to obtain accurate pressure readings with minimal maintenance needs. The analog design allows for easy interpretation without requiring external power, and it maintains high accuracy across its full scale range.

Q: How do I maintain accuracy in my measurements?

A: Maintain the manometer's accuracy by keeping the acrylic tube clean, ensuring the gauge fluid is at the correct fill, and preventing any air bubbles. Always use with the designated fluid, and avoid using at pressures above the capacity (3 Inches WC) to prevent calibration drift.

Q: What should I do if the manometer's reading seems off?

A: If the readings appear inaccurate, check for air bubbles in the liquid column, confirm the manometer is mounted level, and verify the integrity of the rubber tubing and seals. Refill or replace the red gauge fluid if necessary and consult the manufacturer for further troubleshooting if issues persist.
