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.
