The HHF1000 series handheld air
measures and displays air velocity
and air temperature in research and
development labs, HVAC
applications, and other
manufacturing processes. The
sensor design is based on three
RTD elements, one measures air
temperature and the other two
measures air velocity due to the
heat loss from the RTD sensor as it
cools down by the air flow. The
sensor probe is offered in two
configurations, fixed probe and
remote telescopic probe.
The HHF1000 series offers many
standard features such as high and
low alarm indication, USB PC serial
interface with a Windows based data
logging software, adjustable display
response time, volume air flow
readout, and atmospheric pressure
compensation. The HHF1000
displays the air velocity in different
Engineering units such as FPM,
m/sec, Miles/Hour, and Km/ hour.
The air temperature is displayed in
ºF and ºC.
