TOPCON proudly announces the new GPT-3000LN/GPT-3000N.
The GPT-3000LN can measure virtually anything, of any size or material, within a normal working range of 350m.
- New road function can automatically calculate a complicated spiral curve and a long distance route only by inputting the starting point, terminal point and a curvilinear element.
- Topcon realize easy to push alphanumeric keyboard interval.
Achieved reflectorless distance measurement upto 1,200m (to the Kodak Gray card : white surface) in the long range mode. (GPT-3000N : 250m)
