COMPACT WEATHER STATION
MaxiMet GMX400
Atmospheric measurement with rainfall, no wind element.
GMX400 is GMX300 with optical rainfall added. It covers temperature, humidity, pressure and rain in a 0.5 kg unit, for installations where wind is measured separately or not required.

WHERE IT SITS
MaxiMet GMX400 in the MaxiMet range
The MaxiMet GMX400 is the appropriate configuration where the requirement is air temperature, humidity, atmospheric pressure, rainfall, and the parameters it does not carry are provided elsewhere or not needed.
MEASUREMENT
What the MaxiMet GMX400 measures
The MaxiMet GMX400 is configured to measure air temperature, humidity, atmospheric pressure, rainfall. The MaxiMet GMX400 does not measure wind speed and direction or solar radiation.

BEFORE YOU SPECIFY
Is the MaxiMet GMX400 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 GMX400 provides that configuration at 0.5 kg.
