Wavespectrum Benetech GM8903 Digital Anemometer

An anemometer is a device used for measuring the speed of wind, and is also a common weather station instrument. Hot wire anemometers use a very fine wire (on the order of several micrometres) electrically heated to some temperature above the ambient. Air flowing past the wire cools the wire. As the electrical resistance of most metals is dependent upon the temperature of the metal (tungsten is a popular choice for hot-wires), a relationship can be obtained between the resistance of the wire and the flow speed Hot-wire anemometers, while extremely delicate, have extremely high frequency-response and fine spatial resolution compared to other measurement methods, and as such are almost universally employed for the detailed study of turbulent flows, or any flow in which rapid velocity fluctuations are of interest.Air velocity Range=0 to 30 m/s,Air Temperature Range=0 to 45 °CMain 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 350 records •Backlight •Large LCD display •Audio key pressing alert •Connecting to PC with USB cable
