OTT Parsivel
OTT Parsivel²
Laser Precipitation Measurement
The OTT Parsivel² is an advanced laser-based disdrometer for comprehensive measurement of all precipitation types. Accurate yet economical, the Parsivel² captures both the size and speed of individual precipitation particles and a signal processor classifies the type of precipitation as well as the amount and intensity.
