Weighing rain gauge Pluvio² S

200 cm²SDI-12with RS-485 interface

Overview
The Ott Pluvio² S weighing precipitation gauge measures intensity and cumulative precipitation across a wide range (0 to 3,000 mm/h). Developed from the Ott Pluvio² in a compact design, it captures up to 400 mm on a 200 cm² collecting area. The instrument is virtually maintenance-free, mounts on 2-inch pedestals or 50×50 cm concrete bases, requires little space and can replace conventional rain gauges or tipping buckets without structural work.

Benefits

• Measurement precision exceeding WMO No.8: detects events from 0.03 mm with life-time accuracy of ±0.1 mm and algorithmic data verification; hermetically sealed stainless steel load cell.
• Reliable in extreme conditions: solid-precipitation measurement from -40 to +60 °C; optional orifice ring heater and compatibility with anti-freeze agents to reduce snow/ice errors.
• Low maintenance and long-term calibration: load cell and electronics calibrated for instrument life; built-in alerts for overflow and fault conditions.
• Easy network integration: compact, lightweight, low power consumption; installs on 2-inch pedestals or 50×50 cm bases; USB interface for configuration.
• Improved data integrity: plausibility checks and signal filtration reduce wind and temperature influences.
• Cost-effective across networks: low operating costs, portability and simplified installation lower total cost of ownership.
