It works according to the balance principle, taking account of external factors such as temperature and wind that could distort the results. Both, digital outputs (impulse/0.1 mm and frequency/status) and the serial interface, freely configurable as SDI-12 or RS-485, are available for transferring the data.

High-precision technology and robust design provide high accuracy and complete reliability.

Load cell and sensor electronics are hermetically sealed against damaging environmental influences. We have designed the carrier, bucket and protective housing parts to be particularly robust and we have ensured the use of high-quality materials.

• Accurate and reliable data in all weather conditions
• Fulfills all requirements of WMO-manual 306, No. 8 (WMO = World Meteorological Organisation)
• Measured data can be directly compared to the data measured by the classic Hellmann-rain gauge (bucket without a funnel)
• Measurement accuracy of 0.1 mm - for the whole life of the unit
• Conceived for a precipitation intensity range of 0 to 50 mm/min (3000 mm/h) the OTT Pluvio² reliably measures the drizzle of the temperate zones as well as heavy tropical rains
• Bucket orifice without a funnel - heavy and solid precipitation are also recorded with precise timing
• Ring heating optionally available- no formation of snow caps
• Anti-freeze prevents freezing- operation without compromise even in areas with high levels of snow and frost
• Possiblity of solar power supply- for deployment at self-sufficient measuring stations
• Non-sensitive and robust
• Maintenance work is limited to emptying the collecting bucket, occasional visual checks, and adding anti-freeze as necessary
• System-compatible - measured data, alarm-and error messages are available via standard output interfaces
