PLACOM Roller-Type Digital Planimeters

These planimeters feature 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, these instruments are 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. Each comes packaged in a plastic carrying case with AC adapter (battery included) and operating instructions.
Features a 9.5" pole for convenience and ease of use, and has a computing function that provides measurement readouts in the scale desired (sq.ft., acres, etc.)
