Rain and snow gauge

1. Rain and snow gauge product overview

Rain and snow gauge can measure rainfall in liquid, solid and solid-liquid mixtures. It can monitor all types of precipitation and snowfall over a long period of time.Rain and snow gauge uses high-precision pressure sensing elements, which can automatically measure solid, liquid and solid-liquid mixed rainfall and snow amounts in a long-term, stable and high-precision manner and store relevant measurement data. The use of standard parts design, modular parts and castings ensures the high reliability and low maintenance of the rain 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 the open sampling bucket design, it can accurately measure whether it is a small rain intensity or a large rain intensity. The rain intensity range covered can reach 6~1800mm/h, which makes up for the traditional tipping bucket. The disadvantage of traditional or digital rain gauges is that they have a narrow range for measuring rain intensity.
