The OMEGA™ HHF144 rotating vane hygro-thermometer anemometer is a high quality
instrument providing highly accurate humidity, air velocity, and temperature measurements
in harsh environments via a user friendly and intuitive interface. Applications include manufacturing,
laboratory, computer rooms, environmental control, flow hood monitoring, and other applications
where precise air measurement is required.
