and precision, as well as minimal evaporation influences are guaranteed by modern tipping and heating technologies. The system empties itself and registers all precipitation, thus overflowing is impossible. The 4 cm3 bucket with large measuring volume has been constructed especially for extreme precipitation incidents, such as tropical rainstorms.
