A very precise instrument for quick and accurate determination of area on blueprints, maps, photographs, drawings, etc.Simply follow the outline of the area.The revolution of the measuring wheel in either direction is sensed by the electro shaftencoder which generates pulses which are processed by the custommade LSI.
