The Extech AN100 is a professional thermo-anemometer designed for HVAC, ventilation, and environmental testing. It simultaneously displays air velocity (up to 5906 ft/min) and ambient air temperature (14–140°F), and calculates airflow in CFM or CMM using user-defined duct or opening areas. Features include a 2.83” low-friction ball-bearing vane on a 3.9ft cable, 20-point averaging, large backlit LCD, and Min/Max/Data Hold functions — ideal for duct balancing, fume hood verification, and airflow diagnostics.
