Manometers are ideally suited for air velocity
and air filter gage applications at minimal cost.
These inclined manometers provide linear
calibration and excellent resolution throughout
their ranges. They are capable of pressure
measurements above and below atmospheric,
as well as differential pressure measurements.
INS TALLATION
Stationary Applications: Mount the Mark Ii
manometer on a convenient vertical surface.
The installation should not be exposed to strong
chlorine atmospheres or solvents such as
benzene, acetone, carbon
instrument is suitable for total internal pressures
of up to 15 psi (100 kPa) and ambient
temperatures of 150
EXCEED THESE LIMITS. At the mounting
location selected,
on a vertical line spaced 2-31/32" apart. Install
the gage with the self-tapping screws provided,
