Description
The HUBER Meteo Station HM30 is a
multifunctional measuring instrument for
acquiring climatic data such as barometric
pressure, relative humidity and temperatures.
The HM30 can also be used as an altimeter.
Thanks to its versatile range of functions and
high precision, it is suitable for a wide range of
applications.

Safety details
The pressure values and overload levels stated
in these operating instructions are not to be
exceeded; otherwise the instrument or a
sensor can be damaged.
The interpretation of the measured
& & & & &
values with reference to the weather
situation is conditional upon
appropriate experience. Never rely
solely on the measured values of an
instrument for assessing the weather
situation. Weather situations can
change rapidly.
A 9V lithium battery should be used
& & & & &
when using the instrument in
temperatures below -10°C. Cold
reduces the capacity of normal
alkaline accumulators, which could
suddenly not be sufficient to operate
the HM30.
The instrument must not be
operated in an environment with a
fire and explosion hazard!
