Total Station
BTS-902EARIII total station, adopt absolute coding technology, improves the performance of angle measurement. Dispense with initializing the vertical angel of zero, save the horizontal angle after power off. It uses the CCD as a receiver and high-speed 32 bit CPU to realize high speed measurement.
Features:
- Reflectorless distance measurement..
- Visible laser instruction, make the beadle faster and more precisely targeting.
- LCD large-screen displays, intuitive the number keys, letter keys
- RS232-C compatible asynchronous serial port data transmission connection.
- The special design for SD card.
