SEM404 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, the tipping bucket, adopts a three-dimensional streamlined design, which makes the tipping bucket turn water more smoothly, and has the functions of self-cleaning dust and easy cleaning. The rainfall can be directly read, without the need for secondary calculation, which is simple and convenient.
The tipping bucket of the instrument is equipped with a constant magnet steel, and the reed switch bracket is equipped with a reed switch. When the instrument leaves the factory, the magnetic steel and the reed switch have been adjusted to a suitable coupling distance, so that the output signal of the instrument is proportional to the number of times the tipping bucket is turned over relation.
