Profilometer
Principle
The instrument measuring principle for rectangular coordinate measuring method, na ang pangalan ay, through the X axis, Z1 shaft sensor, the measured parts of surveying and mapping the surface profile of the coordinates of the point, through the electrical components, will be measured by the sensor the coordinates of the point data transmission to the upper PC, the software of the original coordinate data collected in the survey were mathematical processing, marked with the required engineering survey projects.
