Product Features

The digital image technology is adopted for automatically distinguish the outline boundaries to reduce human errors and improve efficiency.
The imported precision grating system is adopted as the sensory element; with stable performance, low heating power, corrosion resistance, pollution resistance;
With powerful software, it can complete various complicated measurements.
Software data can be input to CAD for processing, enabling the efficient and fast completion of various measurements and drafting's.
The red laser points printed in the workpiece surface can speedily move the measured piece into visual field;
The observation openings of eyepieces are kept and can be speedily replaced;
All the measurements of the angles and the heights realize the digital display;
All adopts LED cold-lighting source, with low heating power and long life.

Applied fields
