China Boif Bts-912er Total Station

Our BTS-912ER Total Station is a reflectorless (free prism) total station designed with a RS232C compatible and asynchronous serial data transfer interface,digital input keyboard and a large LCD screen with text data displayed on it.It adopts the absolute code technology for angle measurement performance.The vertical angle doesn't need to be initialized after the total station is powered on,and the horizontal angle canbe saved without re-orientation even after the electricity is cut off.This total station also adopts CCD as the receiver,high-speed CPU processor,and the circle to achieve the function of angle reading.
WIth simple structure,high reliability and stability,as well as multifunctional software,our total station is widely used for various measurement tasks,such as setting out survey,area computation,resection survey,and accurate measurement of coordinate,suspension height,subtense,eccentricity,as well as repetition measurement of angle,etc.
1.Our total station can support as long as twenty hours for angle measurement because of the high-capacity lithium battery.
2.The infrared laser instructions ensure fast and accurate target collimation.
3.With 2GB SD memory card,the total station can store a large amout of measurement data.
4.The user can freely define the function key according to their specific measurement needs.
