Heated rain gauge Pluvio² L

weighing400 cm²SDI-12

Overview
Ott Pluvio² L is an all-weather weighing precipitation gauge that measures rainfall, snowfall, hail and precipitation intensity using a high-precision load cell and compensation algorithms for wind, temperature and evaporation to ensure accurate long-term measurements.

Key benefits

• Low total cost of ownership: minimal maintenance with 1–2 scheduled site visits per year; suitable for remote or high-mountain installations without mains supply.
• Lifetime factory calibration across the operating temperature range with individually calibrated, hermetically sealed load cell for high reliability.
• Embedded USB for configuration, monitoring, firmware updates and guided accuracy testing via the Pluvio² operating software; SDI-12 interface for data integration.
• Intelligent rim heating with four modes (constant temperature, time-controlled NWS, solid-precipitation controlled, temperature-range controlled) for mains, solar or battery operation.
• High accuracy across the full intensity range supported by a high-sensitivity load cell, high-resolution acquisition and correction algorithms; typical data availability ~99%.
