the sensor (15188) stands up to any comparison with others in its class. Modern tipping and heating technologies guarantee high reliability, precision and minimal evaporation influences. The system empties itself and registers all precipitation, therefore overflowing is impossible. The 4cm3 bucket with large measuring volume has been constructed especially for extreme precipitation incidents, such as tropical rainstorms or longer recording intervals.
- smooth running tipping bucket bearings
- high resolution
- easy installation
- maintenance-free electronics
- fine materials
