Multi-function HVAC air quality measuring device
Kestrel® 4200
Kestrel Pocket Weather Meters
Like the 4100, the Kestrel 4200 has taken the calculations and guess-work out of air flow measurements with automatic air flow readings. The convenient averaging mode ensures accurate CFM readings in any airflow or duct size and shape. For immediate and accurate air flow readings, simply:
1. Enter the duct shape and dimensions.
2. Hold the 4200 in the air flow.
3. Volume air flow readings are displayed... no calculator required!
