COMPACT WEATHER STATION
MaxiMet GMX300
Temperature, humidity and pressure, without the wind element.
GMX300 is the MaxiMet for installations that need atmospheric measurement but not wind. Removing the ultrasonic wind element makes it the option where a wind measurement is already provided elsewhere on site, or is not part of the requirement.
No moving parts
Compact 0.5 kg all-in-one
Temperature, RH and pressure
Measured in one compact housing
One cable, one output string
IP66 rated
-35 °C to +70 °C

WHERE IT SITS
MaxiMet GMX300 in the MaxiMet range
The MaxiMet GMX300 is the appropriate configuration where the requirement is air temperature, humidity, atmospheric pressure, and the parameters it does not carry are provided elsewhere or not needed.
MEASUREMENT
What the MaxiMet GMX300 measures
The MaxiMet GMX300 is configured to measure air temperature, humidity, atmospheric pressure. The MaxiMet GMX300 does not measure wind speed and direction, rainfall or solar radiation.

BEFORE YOU SPECIFY
Is the MaxiMet GMX300 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 GMX300 provides that configuration at 0.5 kg.
