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. It 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 occurs in the uppermost unit, km2, acre, and the measurement can be continued by pulse count display.
