Specifications
1.high-capacity LI-ION battery,twenty hours for angle measurement. 2.infrared laser instructions.3 2GB SD memory card optional
total station BTS-902E
BTS-902E Total Station adopts the absolute coding technology for angle measurement,and can read the absolute angle,thus improving the angle measurement performance.The vertical angle doesn't need to be saved without re-orientation even after the electricity is cut off.This total station also adopts CCD as the reciever,high-speed CPU processor,and the circle to achieve the function of angle reading,WIth simple structure,high reliability and stability,our total station is widely used for virous measurement tasks.
Features:
2.The infrared laser instructions allow for fast and accurate target collimation.
3.With 2GB SD memory card,the total station can store a large amount of measuring data.
