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.

Unit is legit and works and is very nice but I still have to set it up but this is much better than traditional dro displays. It shows the operations for the different functions it has.

Product Description


Advanced Optical Measuring System

0.02mm Absolute Linear Encoder 50.02mm Absolute Linear Encoder 6




1. VS20 Linear encoder using a double T-slot design, which is convenient for users to install and correct the scale body.

2. VS20 Linear scale can be connected to a positive pressure system, the protection level can reach IP65.

3. Linear Encoder has three reference mounting surfaces, which can flexibly fit to various types of machine tools.


VA scale has a small PCB inside the 9 PIN connector, the laser compensation data is store inside, with our LCD Digital display unit, the compensation data will directly load the ECF file (compensation file) into the DRO, accuracy up to ±2μm.



Aging Test


0.02mm Absolute Linear Encoder 7

Easson Optical Linear Scale's reader head need to power on for 24 x 3 hours aging test before assemble,

make sure all linear scale's is reliable working for long time.


100% Laser calibration

0.02mm Absolute Linear Encoder 8

All linear encoder glass scale are individually inspected and calibrated by our in-house laser interferometer to ensure measuring accuracy comply 100% with the specifications.
