Placom Digital Planimeter KP-90N by ASI

The KP90N planimeter measures the area by pulse count of 6 - digit. This method enables a larger cumulative measurement of area (up to 10 m2). The KP90N is a roller-type planimeter and has full calculation functions.This planimeter can measure a larger area by 100 times than an ordinary planimeter, the conventional planimeter has a maximum cumulative area to measure only 0.1 m2.The KP-90N can easily convert the measured area value in to a new area value with a new unit and with a new scale value.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 overflow occurrs in the uppermost unit, km2, acre, the measurement can be continued by pulse count display.
