The Omega® HHF-SD1 combination
hot wire and standard thermistor
anemometer with SD card data
logger has multiple features that
make it suitable to use in such
applications as environmental
testing, balancing of fans/motors/
blowers, air conveyors, clean rooms,
and flow hoods. What sets the
HHF-SD1 apart from other hot wire
anemometers is that it incorporates
a real-time SD card data logger.
The HHF-SD1 measures velocity,
and air temperature, and has an
input socket that accepts a Type J
or K thermocouple that can be used
as a highly accurate thermometer.
The integrated hot wire and standard
thermistors provide fast and accurate
readings-even at low velocities. The
HHF-SD1 is innovative and easy to
operate. Download data from the
SD card into an Excel spreadsheet
without the need for special software.
