*The self-developed high-precision wind speed measurement unit is sensitive and can quickly and accurately measure small wind speeds with good stability, small drift and high accuracy.
*Open-hole flange installation, using high-quality silicone seals, small air leakage, durable.
*The default range is 0~20m/s, and the maximum range is 0~30m/s. 0~20m/s, 0~30m/s, 0~10m/s, 0~15m/s and other wind speed ranges can be set by 
dialing, which can be freely.
*Special EMC anti-interference device is adopted, which can withstand various kinds of strong electromagnetic interference such as on-site frequency converter.
*With wind speed identification direction, easy to install on site.
