The most standard model of “Koizuimi Placom” N-Series has made the excitingly highest attainment in the history of Placom Digital Planimeter KP-90N 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.

Key Features of Placom KP-90N Digital Planimeter

  • Measurement by 6 digit pulse count
  • This N-Series can measure the area by pulse count of 6-digits. This method enables a larger cumulative measurement of an area (Up to 10m²)
  • The maximum cumulative measurement value of 10m²
  • With the measurement by 6-digit pulse count, the N-Series Planimeter can measure a larger area by 100 times than ordinary Planimeter.
  • The conventional planimeter has a maximum cumulative area to measure only 0.1m². If measurement value shows over 0.1m2 when measuring, the display is to be reset to “O”.
  • This requires to register the numbers of how many times these re-settings occur.
  • With the New PLACOM N-Series, there is no need for these troublesome procedures.
  • Easy conversion function of the unit and scale
  • Placom KP-90N can convert easily the measured area value into a new area value in a newly desired unit and with a newly desired scale value.
  • Hold memory function
  • In the cumulative measurement, this Hold Memory function is effectively used. If an error occurs in measuring, press C/AC key. Then the last measured value is appeared by pulse count. Since previously measured values before an error is stored, there is no need for another measurement from the beginning.
  • Automatic shifting of a unit to an upper unit
  • When the measured area value overflows the displayed figures of 8 digits, the measured area value is calculated and displayed by an upper unit. When the overflows occur in the uppermost unit, km², acre, the measurement can be continued by pulse count display.
  • Average value measurement
  • In order to get better result of measurement, Mean value measurement is recommended. This measurement can be easily done on this N-Series.
  • Measurement of an area with different lateral and longitudinal Scale.
  • Auto-power-off function for energy saving
