The visibility and present weather sensor monitor is capable of measuring, simultaneously, the visibility and the cause of it being reduced (fog, mist, smoke, suspended dust, rain, snow and precipitations in general).
There are different models:
SWS-100: Indicates visibility and types of precipitation.
SWS-200: Indicates visibility, types of precipitation and intensity of the same.
SWS-250: Indicates visibility and past and present atmospheric variables.
Also, the HSS range is available especially for use in airports.
As an accessory we present the ALS-2 environmental light sensor that allows the SWS-250 and the HSS range to change the algorithms to calculate visibility depending of the luminosity being measured at the time.
