Fluke 922

922 Airflow Meter

Measures pressure, air flow and velocity for
maintaining balanced and comfortable
ventilation

The Fluke 922 makes air ow
measurements easy by combining
pressure, air  ow, and velocity into a
single, rugged meter. Compatible with
most Pitot tubes, the Fluke 922 allows
technicians to conveniently enter
their duct shape and dimensions for
maximum measurement accuracy.

Use the Fluke 922 to: Ensure proper air
 ow balance and maintain a comfortable
environment; measure pressure drops
across  lters and coils; match ventilation
to occupant loads; monitor indoor vs.
outdoor pressure relationships and
manage the building envelope; and
perform duct traversals for accurate
air ow readings.
