Lutron vane anemometer with a remote 72 mm vane and built-in temperature sensor; measures air velocity 0.4–25.0 m/s.
The Lutron AM4203HA is a practical vane anemometer for anyone who needs quick, dependable airflow readings without a laboratory setup. Its remote vane sits on a lead so you can reach into ducts and grilles while reading the display comfortably in your hand.
Air velocity and temperature together
A built-in temperature sensor means the AM4203HA reports airflow and air temperature at the same time – handy for HVAC balancing and ventilation surveys where both figures matter. The larger 72 mm vane averages gusty flow for steadier, more repeatable results.
