COMPACT WEATHER STATION
MaxiMet GMX600
Wind, temperature, humidity, pressure and optical rainfall in one compact station.
GMX600 combines wind, temperature, humidity, pressure and standard optical rainfall, 0 to 300 mm/hr, in one compact housing. If rainfall accuracy is the priority, the GMX603 adds high-accuracy optical rainfall at 5% or better.

WHERE IT SITS
MaxiMet GMX600 in the MaxiMet range
The MaxiMet GMX600 is the appropriate configuration where the requirement is wind speed and direction, air temperature, humidity, atmospheric pressure, rainfall, and the parameters it does not carry are provided elsewhere or not needed.
MEASUREMENT
What the MaxiMet GMX600 measures
The MaxiMet GMX600 is configured to measure wind speed and direction, air temperature, humidity, atmospheric pressure, rainfall. The MaxiMet GMX600 does not measure solar radiation.
HEATING
What the heating option actually does
Heating on the MaxiMet range is transducer-only and draws around 7 W. It keeps the ultrasonic transducers clear, and it is not equivalent to the full-sensor heating offered on WindSonic M or the WindObserver range.
Where the application involves severe or persistent icing, that is a WindObserver requirement rather than a MaxiMet one.

BEFORE YOU SPECIFY
Is the MaxiMet GMX600 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 GMX600 provides that configuration at 0.8 kg.
