AN300 Large Vane CFM/CMM Thermo-Anemometer by Extech

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).

Features

  • 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): 8.26" (210mm) round and 13.6" (346mm) square
  • Complete with four AAA batteries and hard case

Applications

  • HVAC
  • Manufacturing
  • Engineering
  • Appliance Testing
  • Research and Design
