Electronical polar planimeter HA-300
The polar planimeter is used to measure the area, volume and length on plans, maps, drawing and diagrams etc.
The instrument automatically converts data from the map into actual figures depending on the scale. Five measurement results can be stored in the memory. The instrument is very accurate due to its stable position on the map and yet, it is very easy to handle. Therefore, the planimeter is indispensable for any professional.
Easy to read display and ergonomic keyboard are undoubtedly two of its advantages. A user can read a measurement on the display, store it into the memory, add or subtract form a stored result. Therefore, calculations may be made without the use of a calculator.
Crosshairs enable a quick length measurement without using the pole arm. In order to take a measurement, the crosshair has to be moved along the measured line, and the result will be displayed.
Adjustable tracing arm with a tracing lens is used to measure the area and volume. The lens allows to see the smallest details on a map and to move the arm with better precision using a special grip.
The planimeter set includes charger, a user guide and a case protecting the planimeter during transport and storage, a calibration and calculation accuracy test board.
