Offered in a roller-type model this planimeter features a unique 6-digit pulse count operation that permits cumulative measurement of areas up to 10m-100 times the measuring capacity of ordinary planimeters. Enhanced with advanced micro-processors for accuracy, this instrument is ideal for many applications where precise large area measurements are needed, such as in civil engineering, surveying, forest management, mapmaking and agriculture. Other features include hold and measuring control, clear liquid crystal digital readout, and scale readings in either Metric or English.
