NT-023 Brochure



300m distance measurement with Prism

Redefined the Theodolite by it's small size but strong performance

NT-023 1

2.6 inches LCD Screen with high-capacity battery

Afford a better solution for outside surveying project


                                 Axes Stake Out


The building axes is the basis of constructions. You can choose the relative 

axes to stake out based on the points' position when doing the project. With 

this powerful Axes Stake Out function, NT-023 will help you find the stake 

out point precisely in an easier method.

          Two Methods to Stake Out the Axes


A: Occupied Pt                                         P: Occupied Pt

B: Target Pt                                              A/B: The end of axes

Set NT-023 on one end of the axes        Set NT-023 on an arbitrary point
