Advanced Optical Measuring System
GS90 is special design for the small Lathe, Drilling and Milling machine which has the limited space to install.
The slide carrier of the GS series scales, use a five bearing design for optical grating linear transducer
Sealing Lip
The GS series scales of plastic seals use an innovative material to offer superior oil resistance, high elastic recovery properties and durability, carefully designed lips geometry offer low slide resistance.

100% Laser calibration
All glass grating transducers are individually inspected and calibrated by our in-house laser interferometer to ensure measuring accuracy comply 100% with the specifications.
Accuracy report
Each linear scale is printed with a QR code, which is convenient for users to view the accuracy report of the factory inspection.
FAQ
1. Q: What's your company mainly produce?
A: We are mainly produce CNC Video Measuring Machine, Optical Profile Projector, Digital Readouts(DRO), Linear encoder grating ruler, CNC linear encoder.
2. Q: Did the travel length of GS90 series has over 500mm long?
A: Normally, GS90 travel length is available from the length 50 to 500mm, we don't suggest using this model for long dimension measuring due to its thin scale body structure(Insufficient rigidity).
3. Q: How can I identify Easson GS10, GS30 , GS90 , VS10 and VS20 model?
A: We has the product code label stick on the scale body, also each model deimension is different. For their structure, GS series using a five bearing design and one spring for Optical grating linear scale's carrier；But for VS series, it is totally different with GS which it has 6 spring push & pull structure, more accuracy than GS scale.
4. Q: How long can you produce for the linear encoder ?
A: Maximum is 3000mm.
5. Q: How can I check Easson linear encoder scale accuracy report?
A: User can use the mobile phone which has scanning QR code function(eg. Wechat, browser etc.) to scan the linear scale QR code.
6. Q: What about the products warranty?
A: 13 months from the date of shipment.
