OMEGA’s HHF91 digital anemometer
is a versatile instrument for
measuring air velocity, calculated air
volume flow, and air temperature.
Special features include the ability
to switch measurement units and an
AUTO-OFF function that engages
after 20 minutes (the AUTO-OFF
function can be bypassed for
continuous operation). The HHF91
can indicate average, minimum and
maximum readings, and includes a
hold button to freeze the display.

The kit is supplied with one
handheld readout with attached
velocity probe, one 9V battery,
and one carrying case.
