Benetech GM8901 Digital Anemometer

An anemometer is a device used for measuring the speed of the wind and is also a common weather station instrument. An airflow anemometer combines a propeller and a tail on the same axis to obtain accurate and precise wind speed and direction measurements from the same instrument. The speed of the fan is measured by a rev counter and converted to a windspeed by an electronic chip. Hence, a volumetric flow rate may be calculated if the cross-sectional area is known. In cases where the direction of the air motion is always the same, as in ventilating shafts of mines and buildings, wind vanes known as air meters are employed and give satisfactory results.

Digital Anemometer possesses the following features:

1. Air Velocity & Temperature measurement
2. Max/Min/Average/Current reading
3. ℃/℉temperature unit selection
4. Five units of air velocity: M/s, Km/h, ft/min, Knots, mph
5. Data Hold
6. LCD backlight display
7. Manual/Auto power shut off
8. Beaufort Scale indication
9. Wind chill indication
10. Low battery indication
