Description
Description
The HHF11A anemometer can measure air flow, humidity, dewpoint, wet bulb, air volume, andcapacity. The built-in microprocessorensures high accuracy. It can alsotrack the maximum and minimumvalues along with current readings,displaying the flow rate in the user’schoice of meters per second orcubic feet per minute.
With its low-friction, ball-bearing,mounted-wheel design, the HHF11Ais accurate at both high and low airvelocity. The impeller is accurate to5% FS and can measure the slightestbreeze (0.3 m/s). Other featuresinclude single-point averaging of airvolume and capacity, °C/°Fselection, and auto shut-off after10 minutes of non-use.
