Measures instantaneous precipitation intensities ( mm precipitation / min.) and outputs an intensity-dependant analogue signal. Includes holder to mount monitor to mast or wall.


Precipitation Sensor


This instrument senses the precipitation intensity and provides an instantaneous analogue output. The precipitation is detected optically within a 25cms2 area. The output current is proportional to the precipitation intensity.

Integrated heating avoids problems with snow or freezing.
