JD-02D tipping bucket rain gauge
1 Overview
This instrument is a multi-layer tipping bucket gauge, and its performance meets the national standard GB/T11832-2002 "tipping bucket rain gauge", as well as the China Meteorological Administration's "Guidelines for Meteorological Instruments and Observation Methods" (Sixth Edition) and related requirements.
This instrument adopts the patented technology of cascade controlled release funnel (patent number: ZL.1), which effectively improves the quality of precipitation data observation.
This instrument can be connected to a data collector or computer for various types of meteorological stations, hydrological stations, and rainfall observation stations to accurately measure the start and end time, cumulative precipitation, and precipitation intensity of precipitation.
