Extech AN500 Anemometer

The Extech AN500 anemometer's new sensor technology delivers major improvements in durability and automatic temperature compensation (ATC) for accurate in-duct air velocity measurements with changing air temperatures. The telescoping probe with ruler label ensures that measurements are made in the center of the duct even if out of reach. An ergonomic directional handle and anti-rotation sensor confirms that probe direction and airflow direction are aligned for confident readings.
