COMPACT WEATHER STATION
MaxiMet GMX301
Temperature, humidity, pressure and solar radiation, without the wind element.
GMX301 measures air temperature, humidity, barometric pressure and solar radiation, with no wind element. It is the option where a site needs irradiance alongside the core atmospheric readings, for example on a solar site where wind is measured elsewhere or not required.

WHERE IT SITS
MaxiMet GMX301 in the MaxiMet range
The MaxiMet GMX301 is the appropriate configuration where the requirement is temperature, humidity, pressure and solar radiation, and wind and rainfall are measured elsewhere or not needed.
MEASUREMENT
What the MaxiMet GMX301 measures
The MaxiMet GMX301 measures air temperature, relative humidity, barometric pressure and solar radiation. It derives further parameters from these, including dew point, pressure at sea level, heat index and sunshine hours. The MaxiMet GMX301 does not measure wind speed and direction or rainfall.

BEFORE YOU SPECIFY
Is the MaxiMet GMX301 the correct configuration?
Before specifying, confirm:
- the parameters the application actually requires
- whether wind is needed at this location or measured elsewhere
- the operating temperature and whether heating is required
- the ingress protection the installation demands
- the mounting arrangement and available space
- the interface and output the receiving system expects
If those match the specification above, the MaxiMet GMX301 provides that configuration at 0.6 kg.
