GAOTek Anemometer with Magnetic Sensor (Over-Load Sign)

This Anemometer with magnetic Sensor (Over-load sign) is designed to measure the wind temperature and the wind speed in the range from 0 m/s to 30 m/s.




GAOTek Anemometer with magnetic Sensor (Over-load sign) is designed to measure wind temperature and the wind speed in the range from 0 m/s to 30 m/s. It is lightweight and equipped with latest magnetic sensing technology which can directly display the air flow speed in LCD display. The anemometer has overload sign which indicates “OL”, low battery indication are its special features. It is a perfect tool for sports event, wind measurement, navigation, HVAC and other areas.
