The HHF11A anemometer can measure air flow, humidity, dew
point, wet bulb, air volume, and
capacity. The built-in microprocessor
ensures high accuracy. It can also
track the maximum and minimum
values along with current readings,
displaying the flow rate in the user’s
choice of meters per second or
cubic feet per minute.
With its low-friction, ball-bearing,
mounted-wheel design, the HHF11A
is accurate at both high and low air
velocity. The impeller is accurate to
5% FS and can measure the slightest
breeze (0.3 m/s). Other features
include single-point averaging of air
volume and capacity, °C/°F
selection, and auto shut-off after
10 minutes of non-use.
