Item Description

The Gill MaxiMet GMX300 is an extremely compact, robust and lightweight solution for accurately measuring weather parameters. Three double-louvered naturally aspirated radiation shields deliver long term highly accurate data. Parameters measured include temperature, relative humidity, barometric pressure, absolute humidity, air density and wet bulb temperature.

The result is an extremely durable and cost effective weather station widely used for applications such as agriculture, health & safety, transport, education, energy and building controls. Richard Paul Russell Ltd. can connect the sensor to the WeatherFile website where data can be viewed using any internet connected device and downloaded for detailed analysis in a CSV file format.
