Ultra long 2000 meter prism free distance measurement

In terms of measurement range, the Nanjing Topcon GTS-1002 continuously breaks through the limit of prism free distance measurement, from 150 meters to 350 meters, then to 1200 meters, and now to 2000 meters, the prism free distance measurement range has always exceeded its competitors by more than twice. The extension of the measuring range brings about a wider range of applications.

Dual optical system

GPT-4000LN uses a dual optical system, one for narrow beam measurement in prism free mode; Another type is wide beam measurement in prism mode. Even under thermal flicker conditions, the beam remains stable during long-distance measurements, ensuring the accuracy and reliability of distance measurements.
