EOAS Scientific Instruments
A disdrometer for rain drops is an instrument for measuring rain drop size distributions continuously and automatically. It was developed because statistically meaningful samples of rain drops could not be measured previously without a prohibitive amount of work. The RD-80 distinguishes rain drop size class by interpreting acoustic signals from rain drops striking the pointed yellow diaphragm.
Place as you would a standard rain gauge. There can be no obstructions normal to the sensor. Place a coarse sponge mat about 1/2-1" thick around the sensor to prevent rain from splashing the instrument.
