PitotTube, 30.48 cm
Measures pressure, air flow and velocity for
maintaining balanced and comfortable
ventilation
The Fluke 922 makes airflow
measurements easy by combining
pressure, air flow, 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
flow balance and maintain a comfortable
environment; measure pressure drops
across filters and coils; match ventilation
to occupant loads; monitor indoor vs.
outdoor pressure relationships and
manage the building envelope; and
perform duct traversals for accurate
airflow readings.
• Provides differential and static pressure,
air velocity and flow readings
• Convenient colored hoses help you
properly diagnose pressure readings
• Bright, backlit display for clear viewing
in all environments
• Min/Max/Average/Hold functions for
easy data analysis
• Auto power off saves battery life
