GMX501 Compact Weather Station Description
The Gill MaxiMet GMX501 combines the GMX101, GMX200 and GMX300 into a single unit. It is extremely compact, robust and lightweight, enabling accurate measurement of wind speed and direction, solar radiation and a wide range of weather parameters.
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.
A thermal sensor protected by a single glass dome records the quantity of light per metre calculating solar radiation (W/m2), sunshine hours, twilight, sunrise, sunset, position of sun, solar noon and angle of tilt.
In addition, a 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.
There are also versions of the GMX501 with optional heating please contact sales@rpr.co.uk.
The result is an extremely durable and cost effective maintenance free wind, weather & solar radiation monitoring station, widely used for applications such as solar panel management, agriculture, health & safety, transport, education, energy and building controls.
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.

Precipitation Care & Maintenance
NOTE: the temperature, humidity and barometer sensors are located internally and are not maintainable or replaceable by a user. Consideration should be given to checking the pressure readings against a standard every 12 months and maintaining the temperature and humidity sensor every 12-24 months. If required you can return the MaxiMet to Richard Paul Russell Ltd to check the barometer calibration, please contact us at sales@r-p-r.co.uk for more details.
