Innovative Weather Monitoring Especially ideal for mobile installations, Magellan MX Weather Stations combine the convenience of an all-in-one multi-parameter weather sensor with an internal compass and GPS. Four different models offer sensor options including: Ultrasonic wind speed and direction measurement A combined temperature, pressure, humidity instrument mounted inside three double louvered, naturally aspirated radiation shields Optical rain gauge provides measurements based on the size and number of drops MX600: rain gauge, ultrasonic wind speed and direction, temperature, relative humidity, air pressure, compass, GPS MX500: ultrasonic wind speed and direction, pressure, temperature, relative humidity, compass, GPS MX300: pressure, temperature, relative humidity (no compass or GPS) MX200: ultrasonic wind speed and direction only, compass, GPS Magellan MX Weather Stations Feature Weather-protected sensor unit designed for maximum portability and utility GPS for compensated wind speed Automatic self-alignment of wind direction using internal compass No mechanical components means virtually no maintenance Low power consumption â?? ideal for battery or solar-powered installations One-year warranty Sensor Specifications Temperature Range: -40 to +70'C (-40 to +185'F) Accuracy: 0.3'C (20'C); 0.54'F (68'F) Resolution: 0.1'C (0.18'F) Units: 'C, 'F Barometric Pressure Range: 8.85 - 32.48 inHg (300 - 1100 hPa) Accuracy: 0.015 inHg (0.5 hPa) @ 77'F(25'C) Resolution: 0.003 inHg (0.1 hPa) Units Available: kPa, hPa, mbar, inHg Wind Speed Range: 0-134mph (0-60 m/s) Accuracy: 3% 0.02 mph to 90 mph (3% 0.01m/s to 40 m/s), 5% above 90 mph and up to 134 Resolution: 0.02 mph (0.1 m/s) Units Available: knots, mph, km/hr, m/s Wind Direction Range: 0 to 359' Accuracy: 3' 0.02 mph to 90 mph (0.01 m/s to 40 m/s), 5' above 90 mph and up to 134 mph (40 m/s and up to 60 m/s) Resolution: 1.0' Relative Humidity Range: 0 to 100% Accuracy: 2% 68°F (10%-90% RH) Resolution: 1.0% Precipitation Accuracy: 2% at
