Item Description
The Gill MaxiMet GMX531 combines the GMX101, GMX200 and GMX300 with a Kalyx tipping bucket rain gauge. It isideal for measuring a full set of weather parameters, including precipitation in extreme heavy tropical downpour locations.
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. Additionally a Kalyx tipping bucket rain gauge with a 20m cable provides the ultimate in precipitation measurement.
The 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.
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.
The result is a complete state of the art weathering monitoring solution widely used for applications such as agriculture, health & safety, transport, education and energy.

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.| User Manual | |
