1.Product introduction of Precipitation weather phenomenon instrument

Precipitation weather phenomenon instrument is a meteorological observation system used to observe the weather. It uses the forward scattering principle of light to identify drizzle, rain, sleet, snow, hail, etc.The Precipitation weather phenomenon instrument 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 change 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 Precipitation weather phenomenon instrument

The Precipitation weather phenomenon instrument adopts an integrated design, is small in size 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; optional professional Application software is used to receive instrument observation results and graphically display the raindrop spectrum; a calibration device is optional.

3.Application fields of Precipitation weather phenomenon instrument

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.
