Measuring principle
 
Pluvio2 uses a high-precision electronic weighing principle for all types of precipitation measurement. The high-precision weight sensor can measure the rainfall intensity at the same time, and the internal electronic balance system can also measure the amount of rain evaporation (0.01 mm) with high precision. Equipped with inverted siphon type automatic drainage system and heating device, it is not affected by external weather changes. Low power consumption intelligent output, solar power or 12V battery power supply can work normally.
 
In winter, antifreeze can be added to the rain bucket to measure snowfall. The snow melted directly in the rain bucket will not accumulate and freeze. The instrument is equipped with wind compensation and precipitation detection functions, and can be used normally in strong wind areas in time. In addition, windshield shield accessories can better adapt to the northwest and other regions with large wind and sand.
