An anemometer is a device used for measuring the speed of wind, and is also a common weather station instrument. The term is derived from the Greek word anemos, which means wind, and is used to describe any wind speed instrument used in meteorology.FEATURES:Vane anemometer with simultaneous display of Air Flow or Air Velocity, plus Ambient TemperatureCalculates air volume in CFM or CMMEasy to set area dimensions are stored in the meter's internal memory for the next power onThe Vane Anemometer has 8 memory locations for CFM and 8 for CMM for storing commonly used area sizes20 point average for Air FlowFeatures data hold and min/max/avg functions3% velocity accuracy via low friction 2.83 in (72 mm) diameter ball bearing vane wheel on 3.9 ft (120 cm) cableAnemometerSPECIFICATION:This meter is a digital anemometer for measuring The ambient temperature, humidity, dew point Temperature, wet bulb temperature, wind speed, And air volume.
