Features of Handheld Digital Anemometer Lutron AM-4202: This Air velocity meter provides fast, accurate airflow readings with a clear digital display and features a remote sensor for convenient, separate measurements. Supports multiple air velocity units including m/s, km/h, ft/min, and knots for versatile airflow measurement across different applications. Equipped with temperature measurement capability, allowing readings in both °C and °F. Designed with a low-friction, ball-bearing vane system that ensures stable and precise readings at both high and low air velocities. Traditional twisted vane arms, which often reduce accuracy and reliability, have been completely eliminated to provide consistent performance. Includes a Data Hold function to freeze the displayed reading for easy recording and analysis. Built with a compact and durable housing, making it ideal for field use and easy portability.
