Deck/Nautical Equipment/370231 PLANIMETER DIGITAL WITH CASE, PLANIX-7

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 shaft-encoder which generates pulses which are processed by the custom-made LSI.

数字求积仪：这是一种非常精确的仪器，可以快速准确地确定蓝图、地图、照片、图纸等上的面积。只需按照区域的轮廓操作即可。测量轮在两个方向上的旋转均由电轴编码器检测，该编码器产生脉冲，并由定制的大规模集成电路进行处理。
