Gill MaxiMet GMX550
GMX550 Compact Weather Station
The Gill MaxiMet GMX550 combines the GMX200 and GMX300 with the addition of a side connector to add any rain gauge, the measurements are included in the data string of the sensor.
Three double-louvered naturally aspirated radiation shields deliver long term highly accurate weather data. Parameters measured include temperature, relative humidity, barometric pressure, absolute humidity, air density and wet bulb temperature.
The solid state ultrasonic sensor provides extremely accurate wind speed and direction measurements. An electronic compass comes as standard which delivers apparent wind, WMO wind averages and gust data.
The optional GPS adds the benefit of a true wind measurement, height above sea level, latitude, and longitude, and simplifies installation by automatically finding north.
Richard Paul Russell Ltd. can connect the sensor to the WeatherFile.com website where data can be viewed using any internet connected device and downloaded for detailed analysis in a .CSV file format.
