Laser raindrop spectrometer

1、Laser raindrop spectrometer Product Introduction

Laser raindrop spectrometer is an automatic, continuous sensor that monitors precipitation particles to measure rainfall intensity, raindrop size, and raindrop velocity.The YD1 type Laser raindrop spectrometer is a domestically developed high-precision precipitation detection device. It can identify various rain and snow conditions, surpassing traditional rain gauges and meeting the requirements for precise observation of rain and snow. Utilizing high-precision laser technology, it achieves high-precision detection of rainfall, snowfall, and hail. It is currently one of the most advanced weather phenomenon detection devices internationally, with technology reaching international advanced levels. It features stable performance, high detection accuracy, and unattended operation, meeting the operational requirements of professional meteorological observation. Measurable precipitation types include: drizzle, showers, rain, sleet, snow, sleet, freezing rain, hail, and all other weather phenomenon indicators.

2、Laser raindrop spectrometer Working Principle

The YD1 type Laser raindrop spectrometer is based on the principle of precipitation particle attenuation of linear laser light. Utilizing optical spectroscopic processing technology, it can accurately measure the diameter, velocity, and distribution density of precipitation particles (liquid, solid, and mixed) as they instantaneously pass through the laser surface. Combined with extensive software calculations and analysis, it gathers raindrop spectrum indices to measure meteorological parameters such as rainfall intensity, cumulative rainfall, weather phenomena, and visibility, achieving an accuracy rate exceeding 95%. This powerful instrument can measure over ten meteorological parameters, making it a high-performance meteorological instrument integrating all-weather rain gauge, weather phenomenon identification, and visibility measurement functions.
