Weather Stations with Multiple Remote Sensors

OSI's modular weather stations, such as the OWI-432 WIVIS and MAWOS, are factory-configurable and designed to interface easily with additional or new sensors. However, interchangeability depends on communication protocols and physical compatibility. OSI sensors use standard RS-232, RS-485, and Ethernet interfaces, which facilitates integration with third-party sensors. Contact OSI's technical team to confirm compatibility for your specific configuration.

OSI weather stations measure a comprehensive range of parameters including wind speed and direction, temperature, relative humidity, barometric pressure, dew point, visibility, precipitation type and rate, and present weather conditions such as rain, snow, drizzle, and freezing precipitation. Specific parameters depend on the model and sensor configuration selected.

Yes. The OWI-432 WIVIS and MAWOS systems support flexible power options including solar panels and battery power, making them well-suited for remote and off-grid deployments. The HazMet-100 is also battery and solar compatible. These systems are designed for unattended, continuous operation in extreme climates from Antarctica to tropical rain forests.

No field calibration is required for OSI systems. Advanced DSP electronics and environmentally adaptive algorithms eliminate the need for scheduled calibration. The all-digital, no-moving-parts design also removes the need for regular cleaning of optics. Built-in continuous self-test and self-diagnostics monitor system performance automatically, achieving MTBF in excess of 80,000 hours.

Yes. The AWOS-AV is FAA-certified and complies with FAR 91.171, FAR 91.175, and ICAO standards, making it suitable for official aviation weather observation at airports and helipads. The MAWOS and OWI-432 comply with NWS and WMO weather code standards. OSI systems are also ISO 9001:2015 and CE certified.

The HazMet-100 Portable Hazardous Meteorological Station can be fully set up and transmitting atmospheric data in less than 5 minutes, without any tools required. It arrives in a wheeled hard case with all accessories included and integrates directly with EPA's ALOHA dispersion modeling program, making it ideal for rapid-response hazmat and emergency scenarios.
