The JOANNEUM RESEARCH two-dimensional video raindrop spectrometer is used to monitor rainfall conditions.

This instrument is suitable for research and application fields such as meteorological monitoring, hydrogeology research, and airport weather condition analysis.

This instrument performs linear scanning of high-speed moving objects based on two cameras, recording the detailed status of precipitation.

Sensors are composed of cameras and lighting components. The cameras will perform linear scanning on the images of the measurement area, transmit the images within the collection area to the electronic unit for processing and storage, and then use professional supporting software for data analysis.

The supporting software has powerful functions and a friendly interface, which can analyze the total amount, size, intensity, movement speed, raindrop shape, raindrop spectrum distribution, and horizontal deviation direction of precipitation.
