1.SD CARD MEMORY.
2.LCD large-screen displays,
3 Reflectorless distance measurement

total station BTS902ELARIIIS

BTS-902ELARIIIS 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:
1. Reflectorless distance measurement..
2. Visible laser instruction, make the beadle faster
and more precisely targeting.
3. LCD large-screen displays, intuitive the
number keys, letter keys
4. RS232-C compatible asynchronous serial port
data transmission connection.
5. The special design for SD card.
