The OMEGA® HHF141 rotating
vane anemometer is a high-quality
instrument providing highly accurate
air velocity 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.
