HAFF Planimeters are fitted with a large, crystal-clear tracing lens, and a setting wheel with which to zero the scales. The lens enlarges the view of the wheel, and any gearing, is chosen so that the reading is directly in miles or kilometers. Types and construction of Planimeters: Polar planimeter. The polar USING THE POLAR PLANIMETERS. A Polar Planimeter can be used in two ways : Either. (0) with the Pole outside the figure to be evaluated, or. A planimeter will give correct results for "any" scale factor whatsoever, at least within the tolerance imposed by the operator and a small mechanical Topcon offers four digital planimeter models that allow you to take area and line measurements from maps and other sources with an accuracy within ±0.2Tools for this type of measurement include planimeters, digitizer-computer setups, digitizers with built-in area measuring capability, and grid overlay the various forms of harp planimeters. On the other hand an integrating planimeter determines the area exactly via integral calculus. The
