Anemometer with Beaufort scale, wind direction display, measuring range 0.3 to 45.0 m/s, data storage for 960 measured values, software for transferring the measured values, speed and volume flow measurement, optionally with ISO calibration certificate. The anemometer determines the wind speed via a impeller with a diameter of 65 mm. The anemometer can reliably determine the speed in a measurement range from 0.3 to 45.0 m/s. In addition to the speed measurement for the anemometer, a volume flow measurement can also be performed. A Beaufort scale is stored next to the normal measured value display for the anemometer. The Beaufort scale on the anemometer indicates the degree of wind strength directly. Depending on the orientation of the impeller, the wind direction can also be determined with the anemometer. This is made possible by the gyroscope installed in the flow sensor of the anemometer. At the same time, the current ambient temperature between 0 and 45 °C is displayed on the anemo
