Dwyer Series MARK II M-700PA Manometer Inclined/Vertical Manometer
Dwyer (10-0-700Pa) Mark II 40-25MM Red Oil Gauge
The Dwyer Mark II M-700Pa inclined differential manometer with red
gauge fluid has a 10-0-700 Pa measuring range, built in zero level
and molded plastic case for monitoring air velocity and air filter
performance, and taking pressure measurements above and below
atmospheric pressure. Red gage fluid is freeze-proof and has lower
evaporation rate for use in cold environments, and produces
expanded scale viewing for improved reading resolution. The
built-in zero level provides linear calibration. The manometer has
a styrene-acrylonitrile housing, indicating tube, and fluid wells
for strength and durability. The molded ABS knobs and zero adjust
plunger and shock-mounted glass level vial are wear-resistant.
Leakproof O-ring seals and overflow tank reduce the risk of fluid
loss. Scales are lithograph printed on aluminum to ease reading,
and are epoxy coated to protect against wear. The manometer can be
mounted on any vertical surface.
Dwyer Mark II Manometers come in a variety of ranges. Make sure the
fluid being used is for the correct manometer.
Mark II #25, 27, MM-80 and M-700 Pa use red gage fluid (specific
gravity 0.826).
Mark II #26, 28 and MM180 use blue gage fluid (specific gravity
1.9).
INSTALLATION
Position manometer on a vertical surface. Drill two 1/8˝ or 9/64˝
holes on a vertical line 3-15/16˝ apart. Loosely mount manometer
with self-tapping screws provided. Adjust gage until level bubble
is centered in level vial, then secure the manometer tightly.
For portable use, order optional A-612 Portable Stand.
FILLING
Turn the zero set knob counterclockwise until it stops, then turn
clockwise 3 full turns. This puts zero in approximately the middle
of the travel adjustment in either direction. Remove the fill plug
and fill with gage fluid until fluid reaches zero on scale. Minor
adjustments can be made to adjust zero by adjusting zero knob.
Replace fill plug. If gage is overfilled, remove excess by
inserting pipe cleaner through the fill port to blot up excess
fluid.

Manometers measure the pressure of a liquid or gas. They are used
in laboratory, medical equipment, engineering, automotive, and
heating, ventilation, and air-conditioning applications. Manometers
measure any combination of gauge, absolute, or differential
pressures. Gauge pressure is the amount of pressure in a system
relative to the ambient pressure, absolute pressure is the amount
of pressure in a system relative to an absolute vacuum, and
differential pressure is the difference between two pressures.
Analog manometers are composed of columns of liquid, and they use
gravity and the liquid's density to calculate pressure. Because
they have no moving parts, analog manometers do not require
re-calibration. Digital manometers have pressure sensors that are
connected to a system with a hose to provide a digital readout of
the amount of pressure present in a system. They use
microprocessors to calculate pressure, and they require periodic
calibration to help ensure accuracy.
Dwyer Instruments manufactures measurement and control instruments,
including pressure gauges, flow meters, level instrumentation,
temperature instrumentation, and air quality monitors. The company,
founded in 1931, is headquartered in Michigan City, IN.
