Superior solar measurement performance from the new GMX101 Weather Station

Gill Instruments Limited have announced further expansion of the MaxiMet range of compact weather stations with the launch of a solar only model to help maximise the performance of solar and agro-meteorological installations.

The new station, the GMX101, is the latest model in Gill’s range of MaxiMet compact weather stations which features an integrated Hukseflux net pyranometer to measure solar radiation. The highly accurate instrument uses a glass protected thermal sensor to provide the amount of light up to 1600 watts per metre².

The GMX101 offers additional benefits over similar sensor types including wave length sensitivity of 300-3000nm covering both long and short wave solar radiation, ISO 9060 2nd Class compliance for recognised accuracy standards, and a built-in digital inclinometer with real-time output to aid installation, maintenance and data quality monitoring.

Uniquely the GMX101 also features many additionally derived parameters, such as sunshine hours calculation without the need for an external logger to provide automatically derived parameters including twilight, position of the sun, sun rise, sunset and solar noon.

Designed for use in agro-meteorological applications and monitoring solar PV panel performance, MaxiMet GMX101 offers users with a superior performance weather station dedicated to tracking solar radiation. “The GMX101’s compliance to WMO Guidelines and ISO 9060 standards give our solar customers confidence that its outputs will be the most reliable available.” says Adam Jolliffe, Applications Specialist at Gill Instruments.  “The new model will be a key instrument in helping to maximise efficiency and improve performance via accurate weather data management.”

MaxiMet GMX101 will be launched on stand 5055 during Meteorological Technology World Expo in Madrid, Spain from 27th -29th September 2016. For more information on MaxiMet’s variants for solar applications, please see



Fantastic achievement by Saildrone to gain a Guiness World Record for the highest wind speed recorded by a USV. We're very proud to say they chose a Gill WindMaster 3-axis ultrasonic anemometer as part of their Saildrone platform to measure wind speed and direction.
