Lasico Planimeters are used for measurements of areas of any shape from plans, maps, recorder diagrams, photographs, x-rays, etc. With an area measuring tool like a planimeter, simply trace the outline of an area with a cursor to obtain its square area measurement. If you have a product that is not flat, sometimes you can lay it on a copy machine and make a copy, then use the copy to trace your area. Planimeters are available with mechanical or electronic measuring mechanisms. If you want to measure area, then a planimeter is the perfect tool for the job.
