Extech AN320 Large Vane CFM/CMM Anemometer/Psychrometer and CO2

• • Large 4" (102 mm) vane for increased precision on large air ducts
  • Measures air velocity and airflow
  • Displays airflow and ambient temperature simultaneously
  • Contains built-in thermistor for accurate air temperature readings
  • Performs multipoint, point, and timed average calculations
  • Features Min/Max, data hold, and auto power capability
  • Optional cone and funnel adapter kit available
This family of anemometers features a large 4" (102 mm) diameter vane and dual LCD for ease and accuracy. All models measure and display airflow or air velocity and ambient temperature simultaneously. Model AN310 also provides humidity, wet bulb, and dew point readings. model AN320 additionally measures CO2.

Optional AN300-C airflow cone and funnel adapter kit provides a quick and easy means of airflow measurement for common duct sizes.
What's Included:
hard carrying case and four AAA batteries.
