The QCJ-2000 digital planimeter can rapidly measure the area of closed shapes on a plane. It is widely used in agriculture, forestry, geology, exploration, water resources management, urban planning, land surveys, and other fields, serving as a common instrument for engineering and technical personnel engaged in scientific research, production guidance, and area measurement. Scale settings are retained even after power loss, as are unit settings. Both the measured area on the map and the corresponding actual area after scale conversion are displayed simultaneously. Upon completion of measurement, the display can be switched to show results in different units. The instrument automatically calculates cumulative and average values (for up to 99 data sets). Measurement data can be stored and viewed locally, or uploaded via USB to a serial-port terminal.
