OTT Pluvio² S

    • Compact and relatively light precipitation gauge, with a weather resistant collecting bucket for 400 mm of precipitation (200 cm² collecting area)
    • Minimum space requirement – no problem to install on existing 50 cm x 50 cm concrete bases • any suitable vibration-free 2-inch pedestals can be used again
    • The intensity and cumulative data output fulfils the WMO directive No. 308
    • Highly-developed data capture and processing with signal analysis, filtration and noise reduction as well as algorithms that compensate for the influences of temperature and wind
    • Considerable measuring accuracy of ±1 mm, wide measuring range, and a high data accessibility of 99%
    • Output of high precipitation intensities of up to 3,000 mm/h without any time delay
    • Precise capture of the finest precipitation from as little as 0.03 mm of precipitation in an hour
    • Optionally available with adjustable ring heater – prevents the formation of ice or snow caps and keeps the orifice rim free • also deployable in solar operation in reduced voltage mode
    • Various output interfaces (SDI-12, RS-485, pulse/contact), configurable through USB by means of tablet PC or notebook
    • Low overall operation costs – lifelong calibrated ice-free, drift-free and virtually maintenance-free measuring device

    The OTT Pluvio² S is designed for professional use, and is suited for automated and semi-automated measuring networks, especially in locations where only limited space is available.

    Examples

    • Automated meteorological measuring networks
    • Weather observer measuring networks
    • Urban hydro-meteorological measuring networks
    • Precipitation stations for flood warnings and precipitation-runoff modelling
    • Precipitation stations as part of research projects
    • Weather radar systems for calibration and Z/R correlation
