Solar Powered Rain Gauges

OSI optical rain gauges deliver 5% accumulation accuracy with a resolution of 0.001 mm. They measure rain rates from 0.001 to 500 mm/hr (with extended range options available over 500 mm/hr), making them suitable for both light drizzle detection and extreme precipitation events without evaporation or wind-induced errors.

No field calibration is required for OSI's DSP-based optical sensors. Environmentally adaptive algorithms automatically compensate for dust, water droplets, and ice or snow on the lenses. Typical field calibration intervals for models such as the ORG and APG are approximately every two years, significantly reducing operational overhead.

Yes. OSI solar powered rain gauges are engineered for all climates, with an operating temperature range of -50°C to 60°C (-58°F to 140°F). They have been deployed and proven in environments as extreme as Antarctica and tropical rain forests, with dual self-regulating lens heaters preventing frost, dew, and snow accumulation on optics.

Beyond rain measurement, OSI's All Precipitation Gauges (APG) and weather identifier sensors detect and discriminate between rain, snow, drizzle, freezing drizzle, freezing rain, hail, ice pellets, and mixed conditions. They report over 10 to 60 NWS and WMO weather identification codes, depending on the model selected.

OSI solar powered sensors support a range of communication interfaces including RS-232, RS-485, Ethernet, MODBUS RTU, Limited Distance Modems (LDM), and optional cellular modems. This flexibility enables seamless integration into existing SCADA systems, weather networks, and remote data acquisition platforms for real-time data retrieval from any location.

Yes. OSI sensors hold ISO 9001:2015 quality system certification and CE certification. Select models, including those used in AWOS systems, comply with FAA, NWS, and WMO standards. OSI's sensors are trusted by the FAA, NOAA National Weather Service, U.S. military branches, NASA, and state Departments of Transportation across the USA.
