COMPACT WEATHER STATION
MaxiMet GMX240
Wind and rainfall from one compact station.
GMX240 adds optical rainfall measurement to the wind-only GMX200 without changing the footprint or the weight. It suits installations that need wind and rain together but do not require temperature, humidity or pressure.

Optical rainfall sensing
Optical, 0 to 300 mm/hr
Ultrasonic wind sensing
0 to 60 m/s, no moving parts
2-axis compass built in
Wind plus rain in 0.5 kg
One cable, one output string
IP66 rated
WHERE IT SITS
MaxiMet GMX240 in the MaxiMet range
The MaxiMet GMX240 is the appropriate configuration where the requirement is wind speed and direction, rainfall, and the parameters it does not carry are provided elsewhere or not needed.
MEASUREMENT
What the MaxiMet GMX240 measures
The MaxiMet GMX240 is configured to measure wind speed and direction, rainfall. The MaxiMet GMX240 does not measure air temperature, humidity, atmospheric pressure or solar radiation.

BEFORE YOU SPECIFY
Is the MaxiMet GMX240 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 GMX240 provides that configuration at 0.5 kg.
