Data Logging Hot Wire Airflow Volume Anemometer with "K/J" Port


Data Logging Hot Wire Airflow Volume Anemometer with "K/J" Port

The #HWA2005DL airflow volume anemometer can measure and log the output of exhaust fans and blowers. The hot wire sensor at the end of its telescoping probe can detect breezes as gentle as 40 ft./min (0.2 m/sec), making it ideal for low-airflow applications.
