The visibility gauge is a device used for measuring visibility.
This measuring instrument consists of a transmitter and a receiver and determines the meteorological optical range by measuring the coefficient of transmission or extinction of the atmosphere.

For more of an explanation on visibility measurement, see this paper by Météo France.


Several types of visibility gauges can be installed depending on the desired accuracy and the usage environment: METEO OMNIUM can tailor the type of sensor to be installed depending on the situation.
