Fluke 922 Micromanometer/Air Flow Meter

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
