- U-tube manometer with red or green color concentrate measures positive, negative, and differential pressure for determining velocity and static pressures, leakage, fan and blower efficiency, filter resistance, and pressures.
- Columns composed of 1/8" outside diameter flexible and shatterproof clear butyrate tubing for use with water, red fluid, or mercury (sold separately).
- Choice of calibration in inH2O or mmH2O using water for use with fluorescein green concentrate or mercury (sold separately), or red gauge fluid.
- Choice of measuring range with 1/10 inH2O (2mmH2O on metric units) graduations silkscreened in jet black on stark white scale to ease reading.
- Includes one bottle of red or green gauge fluid.
Dwyer 1222 series Flex-Tube U-tube type manometer uses red gauge
fluid, or mercury or green color concentrate to provide
positive, negative, and differential pressure measurement for
determining velocity and static pressures, leakage, fan and
blower efficiency, filter resistance, and pressures. The
columns are composed of 1/8" outside diameter flexible and
shatterproof clear butyrate tubing for use with colored water,
red fluid, or mercury (sold separately). The manometer is
calibrated in inH2O or mmH2O using water and is available in
W/M-style for use with fluorescein green concentrate or mercury
(sold separately), or D-style for use with red gauge fluid. The
water column has 1/10" divisions for inch scales or 2mm for
metric units. Units are silkscreened in black on a white
background to ease reading. The manometer has magnetic clips to
on vertical surfaces and a clamp bar to prevent slipping.
Magnets are removable to customize ing. The manometer
includes a bottle of fluorescein green or red gauge fluid.

Manometers measure the pressure of a liquid or . 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 a of pressure
in a system relative to the ambient pressure, absolute pressure
is the a 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 a 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.
