1. Product introduction of laser raindrop spectrometer
The laser raindrop spectrometer is a precision instrument for monitoring rainfall intensity and other aspects. The laser raindrop spectrometer uses the principle of laser active detection to accurately measure precipitation (liquid, solid, mixed) particle diameter, speed, distribution density, rain intensity, accumulated rainfall, and weather phenomena. , visibility and other meteorological parameters. FT-YD1 precipitation weather phenomenon meter /laser raindrop spectrometer is a sensor that automatically and continuously monitors precipitation particle spectrum and precipitation weather phenomenon types. Its working principle is to actively emit an infrared light band, calculate the spectral distribution of the falling speed and size of precipitation particles by measuring the changes in light energy received when precipitation particles pass through the light band, and automatically identify and output precipitation weather based on the empirical model of precipitation particle spectrum. Phenomenon.
2. Functional characteristics of laser raindrop spectrometer
The FT-YD1 laser raindrop spectrometer adopts an integrated design, is compact and easy to install; has stable performance, accurate data, and strong environmental adaptability; the transmitting and receiving ends are covered with unique splash-proof covers to effectively prevent precipitation particles from splashing into the sampling area; it can Optional professional application software is used to receive instrument observation results and graphically display raindrop spectrum; optional calibration device is available.
3. Application fields of laser raindrop spectrometer
It is suitable for scientific research institutes, artificial weather modification and other fields, and can effectively monitor precipitation types and provide early warning for disaster prevention and reduction.
