Optical Rain Gauge


(picture of current model, similar to what we had)

Precipitation measurement based on the shadowing of light across an optical path.  ISFS had three.  We tried also using these for snow measurements, but were unable to get reliable quantitative measurements.  These have been superceeded by ISFS's use of OTT Parsival2 sensors based on a similar principle.
