Today's HVAC technicians need a simple solution for diagnosing ventilation issues. 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.
The Fluke 922 Airflow Meter helps you:
Ensure proper air flow balance
Monitor air pressure across key HVAC components
Promote good indoor air quality
Maintain a comfortable environment
Use the Fluke 922 to:
Measure pressure drops across filters and coils
Match ventilation to occupant loads
Monitor indoor vs. outdoor pressure relationships and manage the building envelope
Perform duct traversals for accurate airflow readings
