Weighing Principle Precipitation Gauge

1.Weighing Principle Precipitation Gauge Product Overview

The Weighing Principle Precipitation Gauge uses high-precision pressure sensing elements to automatically measure solid, liquid, and solid-liquid mixed precipitation and snow for a long time with high accuracy and stability, and store relevant measurement data. The standard design, modular components, and castings ensure the high reliability and low maintenance of the precipitation and snow gauge, making it suitable for all-weather rainfall and snowfall observations in areas with harsh environments. Because it adopts the weighing principle and open sampling barrel design, it can accurately measure both small and large rainfall intensities, covering a rainfall intensity range of 6~1800mm/h, which makes up for the narrow rainfall intensity range of traditional tipping bucket or digital rain gauges.
