The electronic anemometer keeps complexity to itself and brings simplicity to you. Less redundancy, more responsibility. With a minimalist body design, every measurement is carried out with ease. The essence of simplicity applies to wind measurement as well. With just one button, you can understand the wind.

The handheld electronic anemometer is an instrument for measuring speed, widely used in coal mines, transportation, construction, chemical industries, and meteorological observation. It can measure instantaneous wind speed and one-minute average wind speed.
