China Boif Bts-902e Total Station

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.
1.The high-capacity lithium battery of our total station can support as long as twenty hours for angle measurement.
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.
