Wavespectrum Benetech GM8902USB Digital Anemometer

An anemometer is a device used for measuring the speed of wind, and is also a common weather station instrument.. An air flow 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, volumetric flowrate 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 resultsMain Features:•Measurement of wind velocity, temperature and flow •Unit conversion of wind velocity, temperature and flow •Measurement of maximum and minimum wind velocity •Measurement of 2/3 Vmax and average wind flow •Data holding, storing and deleting function •Low battery indicating function •Auto power off function (power off automatically if no further operation for 10 minutes ) •Memory of 500 records •Backlight •Audio key pressing alert •Large LCD display •Connect to PC with USB cable
