ES-W303U เครื่องวัดความเร็วลมแบบอัลตราโซนิคราคาประหยัด

ES-W303U Low cost ultrasonic anemometer is a wind speed and direction measuring instrument developed based on ultrasonic principles. It uses the transmitted sound wave pulses to measure the phase difference at the receiving end to calculate the wind speed and wind direction. The sensor can measure the instantaneous values ​​of wind speed and wind direction at the same time.

The device with built-in electronic compass selection no longer has the requirements for orientation during installation, and only needs to ensure horizontal installation. The whole machine shell is made of high-quality ABS material, which is light in weight and has no moving parts.
