Basic functions of digital display anemometer: It is mainly used to measure environmental wind speed, air volume and rheumatism. The split structure design is adopted, and the connecting line between the fan and the main engine can be extended to a further distance and area, making the operation more convenient. It has the functions of instantaneous, average, 2/3 maximum air volume measurement, wind speed and rheumatism measurement, as well as standard USB computer interface and supporting computer communication software, which can realize real-time measurement and measurement data analysis. * Measurement range: 0.c-45.c * Wind speed measurement range: 0.3-45 m/s * Wind speed measurement error +-0.1dgts * Automatic/manual shutdown * Wind speed unit selection, m/s,Ft/min.knots.km/hr.Mph * With backlight display function * Maximum/minimum wind speed measurement * Average wind speed and current wind speed measurement * Resolution 0.1 m/s * Data retention
