 The AN300 is a Large Vane CFM/CMM Thermo-Anemometer. This meter measures Air Velocity, Air Flow and Temperature. Extech’s Large Vane Thermo-Anemometer series allows for more precise readings on larger size ducts. Each meter simultaneously displays Airflow or Air Velocity and Temperature. Complete with 4 AAA batteries and hard carrying case.  

4″ (10cm) vane allows for more precise readings on larger size ducts

Multipoint and timed average calculations

Complete with four AAA (1.5V) batteries and hard carrying case
