Recognized worldwide for its precision and performance, the OTT Pluvio² is an all-weather precipitation gauge that uses superior weight-based technology to measure rainfall, snow or hail. The OTT Pluvio² determines the collection bucket weight every 6 seconds. The difference between this measurement and the known weight of an empty collection bucket equals the precipitation accumulation. The difference between the current bucket content and the previous measurement equals precipitation intensity. The OTT Pluvio² evaluates each measurement and compensates for external influences such as temperature, wind, and evaporation.
