The OMEGA™ HHF143 rotating vane anemometer series are
high-quality instruments providing highly accurate air velocity and
temperature measurements in harsh environments via a userfriendly
and intuitive interface. Applications include indoor air
quality, process control, flow hood monitoring, and many other
applications where precise air flow and temperature measurement
is required.
