The SWS-250 Visibility and Present Weather Sensor is specifically designed for aviation applications, providing accurate visibility and detailed weather data, including past and present conditions. It measures visibility (MOR, EXCO, TEXCO), fog, haze, drizzle, snow, hail, and other non-frozen precipitation, delivering METAR-coded outputs. With a range extending up to 99.99 km, the sensor is ideal for meteorological observation networks and research. Its backscatter receiver and advanced algorithms ensure precise precipitation analysis, while integration with the optional ALS-2 ambient light sensor makes it perfect for Runway Visual Range (RVR) applications. Easy field calibration and comprehensive self-testing enhance operational reliability.
