AN300/AN310/AN320 Large Vane CFM/CMM Thermo-Anemometers + CO

2

*

4" (10cm) large vane allows for more precise readings on larger size ducts;
choose models that also measure Air Volume, Humidity & Carbon Dioxide

• Fast responding sensors measure Air Velocity and Air Flow

• Built-in thermistor for air temperature

• Multipoint and timed average calculations

• Min/Max, Data Hold, and Auto power off

• Optional Air Flow Cone Kit (AN300-C) allows HVAC technicians to
be freed from the hassle of calculating dimensions and allow for
quick and easy airflow measurments for these common duct sizes;
Adaptor size: Round 8.26" (210mm) and Square 13.6" (346mm)

• Complete with four AAA batteries and hard case; 1 year warranty

AN310 Additional Functions:

• Measures Relative Humidity, Wet Bulb and Dew Point

*AN320 Additional Functions:

• Measures Relative Humidity, Wet Bulb and Dew Point

• Carbon Dioxide (CO
