Accuracy of measurements of the precipitation amount in function of time has been analysed using a traditional pluviograph and a new generation tipping bucket pluviograph (SEBA) in comparison to standard Hellmann's rain gauge. It was based on pluviographic material from IMGW meteorological station in Legnica (warm half-year from May to October 2009). The comparisons were made for 4 typical balance precipitation periods: May-October period, 1 month, 24 h, 360 min. For balance periods: season, month, 24 hours it was considered sufficiently accurate and approximately equal. However the analysis of short term precipitation (up to 360 min) showed that the biggest differences in precipitation amounts occur in the first 5 min of the rainfall time interval. Mutual differences between precipitation at definite time intervals for pluviograph and SEBA pluviograph are the lowest when they are used for interpreting pluviograms of changeable intervals of precipitation time. In the case of very intensive rainfalls, reaching the height of several millimeters during 5 min, it showed an underestimation of about 10-20% of the precipitation height by the SEBA pluviograph in comparison to the traditional pluviograph.
