Main Features and Use:
The telecope is inner focusing with sharp image. Therule is easy to read estimat with high reading precision. The vertical axis is semi-mobile, turing smoothly, high directional preision.
The horizontal standard deviation of one measurement is not larger than ±6″,the vertical standard deviation of one measurement is no langer than ±10°.
The instrument is mainly used for low level control measurement,engineering measurement, wire measurement and construction measurement etc.
