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.
