Product Description
Advanced Optical Measuring System
The slide carrier of the GS series scales, use a five bearing design for optical grating linear transducer which has been proven as the most reliable system design in today's market.
Double Seals Design
The plastic seals of GS series scales 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
Easson linear scale is printed with a QR code, which is convenient for users to view the accuracy report of the factory inspection.
Shipment can be customed, we can also provide cross-border cargo transportation such as LCL, FCL, international express, international air transportation, port trailers, China-Hong Kong transportation etc.
