FLUKE 922 AIRFLOW METER/MICROMANOMETER

The
Fluke 922 Airflow Meter/Micromanometer
is designed to simplify the diagnosis of ventilation issues by integrating three essential tools: differential pressure, airflow, and velocity measurements. This handheld device allows HVAC technicians to:
The Fluke 922 features a bright, backlit display for clear viewing in various environments, user-defined duct shape and size inputs for maximum airflow accuracy, and convenient colored hoses to help interpret pressure readings accurately. Additional functions include Min/Max/Average/Hold for easy data analysis and auto power-off to conserve battery life.
