Marine Grade Weather Monitoring Systems

No. OSI marine weather sensors use optical scintillation technology that is inherently insensitive to dirt, salt spray, and water droplets accumulating on lenses. No scheduled lens cleaning or field calibration is required. The DSP-based design with environmentally adaptive algorithms ensures continuous accuracy without manual intervention, even during extended offshore deployments.

OSI sensors detect and discriminate between rain, snow, drizzle, freezing drizzle, freezing rain, hail, and ice pellets. The APG All Precipitation Gauge and DSP-WIVIS report over 50 NWS/WMO weather codes, while the optional HIPS acoustic add-on sensor enhances hail and ice pellet discrimination — critical for climate research and ocean monitoring applications.

Yes. The ORG Optical Rain Gauge, APG, and LP-WIVIS (OWI-650) are designed for solar and battery-powered operation, drawing only nominal 12 VDC at 400 mA maximum. The OWI-432 Small Weather Station also supports solar and battery configurations, making all these systems ideal for remote data buoys and unmanned offshore installations where grid power is unavailable.

OSI marine sensors operate across a range of -50°C to 60°C (-58°F to 140°F), covering everything from Arctic sea ice monitoring to tropical ocean environments. They have been deployed successfully on every continent, including Antarctica, demonstrating reliable performance across the full spectrum of maritime climate conditions.

OSI sensors support RS-232 as standard, with options for RS-485, Ethernet, MODBUS RTU, Limited Distance Modems (LDM), cellular modems, spread spectrum radios, satellite, and GSM. This flexibility ensures real-time weather data can be transmitted from offshore buoys, research vessels, or remote coastal stations to onshore operations centers.

OSI marine weather monitoring products are backed by ISO 9001:2015 quality system certification and CE certification. Applicable products also comply with NWS and WMO weather code standards. Select systems are FAA certified for aviation use. The company has also earned approvals from NOAA, the EPA, and Environmental Technology Laboratories (ETL) for specific sensor models.
