The DAFM4 In-Duct Anemometer/Hygrometer is a new addition to the UEi product family. This tool will measure airflow, temperature, and relative humidity and emit air volume, dew point, and wet bulb calculations. The small vane (0.7 inch) on a telescopic probe is designed for use in ductwork. The DAFM4 now features timed average for more accurate air volume calculations and supports a new simplified user interface. The meters combine multiple features of other tools in one meter, which makes the DAFM4 a very nice addition to the tool bag, said the company.
