Weighing Rain Gauge

Weighing Rain Gauge complies with WMO 306 No.8 rainfall measurement standard

Weighing Rain Gauge can be used to continuously measure and record rainfall, rainfall duration and rainfall intensity in hydrology, meteorological stations and other related fields.

Weighing Rain Gauge Measurement Principle

Pluvio2 uses a high-precision electronic weighing principle to measure precipitation. The high-precision weight sensor can measure the rainfall intensity at the same time, and the internal electronic balance system

It can also measure the evaporation of rainwater with high precision. It can be equipped with an inverted siphon automatic drainage system and a heating device, which is not affected by external weather changes. Low power consumption intelligent transmission

It can work normally with solar power or 12V battery.

In winter, antifreeze can be added to the rain gauge to measure snowfall. The snow will melt directly in the rain gauge without accumulating or freezing.

The instrument has built-in wind compensation and precipitation detection functions, and can be used normally even in strong wind areas. There are also wind shield accessories that can better adapt to windy and sandy areas such as the northwest.
