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 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
