1. Product Overview
YGM219 micro wind speed transmitter is specially designed for accurate measurement of micro wind speed, which can still maintain good accuracy when the minimum wind speed is as low as 0.2m/s. The probe rod is equipped with a pair or pairs of sample gas collection holes, which can measure the wind speed at a single point or at multiple points. The probe rod has a certain anti pollution ability and can be used under worse working conditions. With LCD display, the current wind speed can be displayed visually. With buttons, it is convenient to calibrate the wind speed and output signal
