Extech AN100 CFM CMM Thermo Anemometer
The Extech AN100 CFM CMM Thermo Anemometer gives fast and reliable air flow readings for HVAC engineers and maintenance teams. It measures both air velocity and air volume while also showing ambient temperature on the large LCD display. The meter stores area dimensions in its memory, making repeated duct testing much easier.
Built with a low friction 72 mm vane wheel, the instrument delivers accurate measurements across a wide operating range. The Extech AN100 CFM CMM Thermo Anemometer also includes a 20 point average mode to provide more stable airflow readings. In addition, the data hold function helps users record results without losing displayed values.
Designed for HVAC Applications
This meter is suitable for ventilation balancing, plant maintenance and environmental testing. Service engineers can quickly switch between m/s, ft/min, km/h, mph and knots depending on the application. Because the sensor is mounted on a 120 cm cable, it is easy to reach vents and awkward measurement points.
Two set options are available for different requirements. Users can select the standard Extech AN100 CFM CMM Thermo Anemometer or choose the AN100-NIST version that includes calibration traceable to NIST standards. Both versions are supplied with essential accessories for immediate use.
Simple and Practical Operation
Memory functions allow up to eight area dimensions to be stored inside the instrument. As a result, engineers can perform repeated airflow calculations without entering dimensions each time. The compact housing and protective holster also make the meter suitable for daily field work.
Whether checking ventilation systems or carrying out routine maintenance, the Extech AN100 CFM CMM Thermo Anemometer provides dependable measurements with straightforward operation. Its combination of airflow, velocity and temperature measurement makes it a practical tool for a wide range of professional applications.
