DIGITAL PLANIMETER

N-Series with the most advanced functions and perfect reliability. The most standard model of "PLACOM" N-Series has made the excitingly highest attainment in the history of Planimeter ever made.Measuring capacity is remarkably enlarged. Measuring by 6-digit pulse count enables to measure 100 times larger accumulative area than ordinary planimeters. Easy calculations of Cumulative and Average Value Measurement. Conversion of Unit and Scale value is made by easy operation. "WONDER", it is a most worthy word to be given to this "PLACOM" N-Series.
