Preliminary inspection is an indispensable component of building renovation or relocation of factory equipment. The GLS-2000 quickly measures and collects precise 3D point clouds without interrupting ongoing operations. High-density 3D point clouds can be widely utilized for generating as-built drawings and simulation of piping or equipment installation. The GLS-2000 can be safely operated even in areas where laser emission power is restricted; simply by choosing the “Low Power” (Class 1M) measurement mode.
