JD Series Projection Length Measuring Machine

Features

->High-quality cast-iron is adopted as base; which has been undergone natural aging treatment to guarantee its sufficient steely property and stability.

->Use Eppenstein optical principle to real-time correction of Abbe errors thus guarantee the accuracy of measurement.

-> A new projection system is adopted for the projecting readout screen to get a clear and sharp images.

-> Worktable can be moved, turned around and deflected in all directions, convenient for the inspection of various shapes of parts.

-> Provide complete range measuring accessories to achieve wide application.
