General description This Digital Wind Speed Anemometer is a multifunctional device designed to measure wind speed and air temperature. It features a wide range of wind speed measurements from 0 to 30 m/s (0 to 5860 ft/min, 0 to 55 knots, 0 to 90 km/h, and 0 to 65 mph) and includes 12 Beaufort scales. The device also detects air temperature ranging from 14°F to 113°F and allows for easy switching between Celsius and Fahrenheit units. The LCD screen displays maximum, average, and current air speed in real time, making it more convenient than traditional 2-button anemometers.
