COMPACT WEATHER STATION

MaxiMet GMX301

Solar radiation measurement as a single-parameter node.

GMX301 measures solar radiation and nothing else. It is the option where a site needs a solar radiation node, for example alongside a station that already covers the other parameters, rather than a full compact weather station.

WHERE IT SITS

MaxiMet GMX301 in the MaxiMet range

The MaxiMet GMX301 is the appropriate configuration where the requirement is solar radiation, and the parameters it does not carry are provided elsewhere or not needed.

MEASUREMENT

What the MaxiMet GMX301 measures

The MaxiMet GMX301 is configured to measure solar radiation. The MaxiMet GMX301 does not measure wind speed and direction, air temperature, humidity, atmospheric pressure 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.

QUESTIONS

Specification questions about the MaxiMet GMX301

Which parameters does the MaxiMet GMX301 measure?

The MaxiMet GMX301 measures solar radiation and GPS.

What is the difference between the MaxiMet GMX301 and the GMX300?
