AN300 Series 
Large Vane CFM/
CMM Thermo-Anemometers
Extech’s 4" (10cm) Large Vane Thermo-Anemometer 
series allows for more precise readings on larger size 
ducts. Each meter simultaneously displays Airflow or 
Air Velocity and Temperature. Choose models that also 
measure Air Volume, Humidity & Carbon Dioxide (CO
2
). 
Applications:
-   HVAC 
- Manufacturing
- Engineering
- Appliance Testing
- Research and Design
- and more!
AN300-C - Cone/Funnel Adapters
The meter has a cone and square preset. 
With this optional kit it would allow HVAC 
technicians to be freed from the hassle 
of calculating dimensions and allow for 
quick and easy air flow measurments for 
these common duct sizes.
