Analyze airflow. Easily. The 922 Micromanometer.

Today’ s HVAC technicians want a simple solution for diagnosing ventilation issues. Differential pressure measurements only tell part of the story. Technicians also want to measure air velocity and flow, without having to resort to expensive, difficult to use, specialist tools. The Fluke 922 makes airflow measurements easy by combining three tools: differential pressure, airflow, and velocity into a single, rugged meter.

Use the Fluke 922 micromanometer to:

Measure pressure drops across key HVAC equipment to drive peak performance and extend equipment life
Match ventilation to occupant loads
Monitor indoor vs. outdoor pressure relationships and manage the building envelope
Promote indoor comfort and quality
Perform duct traversals for accurate airflow readings
