Technical Description


METEO102P 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.

  • How does METEO102P achieve accurate rainfall/snowfall measurement in extreme weather?

    • Its ​electronic weighing core​ delivers precision: ✓ ​Heating & antifreeze system: Melts snow instantly (no accumulation) ✓ ​Wind compensation algorithms: Valid data in storms/sandstorms ✓ ​Evaporation tracking: Measures liquid loss between events
  • Can this operate off-grid with minimal maintenance?

    • Yes – engineered for harsh autonomy: • ​Solar/12V battery operation: Zero grid dependency • ​Auto-drainage system: Prevents overflow in heavy rains • ​Sand-resistant design: Optional wind shield for deserts • 5-year calibration stability
