PLANIMETER AZA1040
The Planimeter AZA1040 from Azalab is a precision instrument designed for accurate measurement of two-dimensional areas on paper maps, plans, charts, drawings, and diagrams. It is widely used in surveying, cartography, civil engineering, architecture, town planning, agriculture, and GIS applications, particularly where irregular or curved boundaries must be measured reliably.
Conventional methods such as grid counting or manual calculation become inefficient and inaccurate when dealing with complex shapes. The AZA1040 Planimeter overcomes this limitation by allowing users to trace the perimeter of any closed figure, instantly converting the traced path into an accurate area measurement.
