SEM400 is a precipitation measurement instrument, and its performance meets the requirements of the national standard GB/T 21978.2-2014 "Precipitation Observation Requirements".
The core component of the instrument is a three-dimensional streamlined tipping bucket made of stainless steel, which makes the tipping bucket turn more smoothly, and has the functions of self-cleaning dust and easy cleaning. It can directly read the rainfall without secondary calculation, which is simple and convenient.
The instrument consists of rain gauge shell, rain collector, funnel, tipping bucket support, tipping bucket, bearing screw, water outlet, sealing joint, dry reed switch, horizontal bubble, adjusting support plate, control box, leveling It is composed of device, terminal, leg bracket, rain gauge base, etc. Among them, a tipping shaft, a circular horizontal bubble, a reed switch bracket and a signal output terminal are installed on the base of the rain gauge. Different from other tipping bucket rain gauges, the tipping bucket bushing of this instrument is an integrated positioning structure, and the tipping bucket is installed in the shaft bearing through the tipping bucket shaft. On-site installation brings convenience.
