Extech 407113 Vane Anemometer for Accurate Airflow Testing

The Extech 407113 Heavy-Duty Metal Vane Anemometer is engineered for robust airflow measurement, capable of recording air velocity from 0.5 to 35 m/s (100–6890 ft/min) with ±2% accuracy. It simultaneously displays air velocity (or flow) along with temperature, showing values from 0 to 80 °C. Its metal vane sensor is mounted on a durable 3.9 ft (1.2 m) cable, built to withstand harsh environments and elevated temperatures (up to 175 °F / 80 °C). The instrument supports three airflow modes — instantaneous, 20-point average, and 2/3 flow — for versatile data capture. Memory functions let you record and recall minimum and maximum readings, while a data-hold feature freezes values for easy viewing. With its automatic power-off function, it conserves battery life, running on a standard 9V battery (or optional AC adapter). The large 9,999-count LCD ensures easy readability, and a built-in RS-232 PC interface allows data export for further analysis. It comes complete with a protective rubber holster (with stand), a hard carrying case, and is well-suited for HVAC testing, ventilation diagnostics, and industrial airflow monitoring.
