The Extech 451181 printing anemometer and hygro-thermometer can measure, data log, download, and print air
flow readings to a PC. The Extech 451181 printing anemometer and hygro-thermometer can simultaneously read
and display air velocity, temperature, humidity, wet bulb, and calculate CFM / CMM.
Measuring air velocity from 60 to 4930 ft/s (or equivalent) with an accuracy of ±3%, the Extech 451181
printing anemometer and hygro-thermometer also measures temperatures from -4 to 144°F (-20 to 60°C) and
humidity from 0 to 100%. The Extech 451181 printing anemometer and hygro-thermometer allows users to manually
log up to 99 readings or setup a time intervals for automatic logging with the built-in data logging function.
The data logger contains date / time stamps and can be used for recall, printing or downloading to a PC at a
later time. The Extech 451181 printing anemometer and hygro-thermometer also includes a thermal printer that
can print readings along with a date/time stamp. An RS-232 PC interface with Windows compatible software
allows quick transfer of data to a PC.
