Customer Reviews
This DRO display is smaller than most and i am very happy with it. The controls are simplified and i have had no problem mastering it and using all features. I'm 71 years old. The Display information is bright white and very easy to see in all lighting conditions even with my poor eye sight. No green or red led lights to have to look at anymore.

High Accuracy Automatic Auto Zoom Vision Measuring Machine With 0.01 micron Absolute Linear Encoder



Product Introduction


Easson AT series Automatic Vision Measuring Machine is an effective length measuring machine constructed by the technology of precision machinery, optic, electronic etc..



Features in the VMM control system of AR- 3 are as follows:

  •  Special processor (ASP) to significantly reduce the number of electronic circuits and parts to improve reliability.
  •  Single circuit board structure, in order to greatly reduce the number of wiring to improve reliability.
  •  High speed and high precision fully closed-loop AC servo control system, which can provide positioning accuracy up   to 1 μm, in order to minimize the possible factors affecting measurement repeatability.
  •  Built in 21 orders of high precision geometric stereo spatial error compensation.
