Applications:
This instrument owns all the functions of TUSE-1002 tunnel section detector; In addition, it can also realize the front and rear section measurements, blasthole indication, surrounding rock convergence measurement and other functions. It makes the job of the construction units and supervision units easier in tunnel construction and tunnel inspection.
Product functions:
 Detect the front and rear tunnel section quickly;
 Deformation measurements: such as convergence measurement;
 Light-spot (blasthole) indication and tunnel contour sampling.
Main features:
 Self-developed PDA : Damp proof and anti-smoking;
 Friendly interface and easy to operate;
 Store the standard section data, and make comparison between current data and standard section data, and real-time display overbreak and underbreak data;
 Use high-precision angle encoder and rangefinder;
 Use special designed PDA without notebook PC on site;
 Powerful post-processing software: easy operation and auto create reports;
 Auto measure instrument height.
