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 (CO2).
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.
