Extech AN100 Anemometer
The Extech AN100 is a versatile handheld instrument designed for HVAC professionals, environmental engineers, and facility maintenance teams. It combines air velocity, airflow (CFM/CMM), and ambient temperature measurements in one device. Featuring a 2.83-inch (72 mm) ball-bearing vane sensor on a 3.9-foot (120 cm) cable, it delivers accurate readings across a wide range of applications, from duct inspections to environmental monitoring.
Description
The Extech AN100 CFM/CMM Mini Thermo-Anemometer is engineered to provide comprehensive airflow and temperature measurements in one compact tool. Its 2.83-inch (72 mm) ball-bearing vane sensor, connected via a 3.9-foot (120 cm) cable, ensures accurate air velocity readings across various environments. The device offers simultaneous display of air velocity or airflow (CFM/CMM) and ambient temperature, facilitating efficient diagnostics and analysis.
The instrument features a 20-point averaging function for airflow measurements, enhancing accuracy over time. It also includes functions such as data hold, min/max readings, and auto power-off to conserve battery life. The AN100 is powered by a 9V battery and comes with a protective rubber holster and carrying case for portability and protection.
For enhanced measurement capabilities, the optional AN100-C airflow cone and funnel adapter kit provides a quick and easy means of airflow measurement for common duct sizes, streamlining the process and improving measurement accuracy.
