Today’s HVAC technicians need a simple solution for diagnosing ventilation issues. The Fluke 922 makes airflow measurements easy by combin- ing pressure, air flow, and velocity into a single, rugged meter. Compatible with most pitot tubes, the Fluke 922 allows technicians to conve- niently enter their duct shape and dimensions for maximum measurement accuracy. The Fluke 922 Airflow Meter helps you:
- Monitor air pressure across key HVAC components
- Ensure proper air flow balance
- 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 Features:
- Powerful meter provides differential and static pres- sure, air velocity and flow readings
- Rugged design built for field use
- Easy to use without sacrific- ing performance
- User-defined duct shape and size for maximum airflow accuracy
- Convenient colored hoses help you properly diagnose pressure readings
- Bright, backlit display for clear viewing in all environments
- Min/Max/Average/Hold func- tions for easy data analysis
- Auto power off saves battery life
