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 between FPM/°F and
m/sec-°C 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. It can also be
reprogrammed with the keypad to
read in either FPM/mps and °C/°F.
The kit is supplied with one
handheld readout with attached
velocityprobe (3 foot cable), one 9 V battery,
and one carrying case.
