Why Can We Always Ensure Excellent Quality

Quality Control

Every piece from Compass must pass 4 quality control steps before delivery: raw material inspection, mid-production inspection, full inspection before packing and warehouse-out inspection. We believe quality is the best advertizement.

With the spectrograph, it makes the material inspection more convenient and faster.

And material certificate must be supplied when we purchase the raw materials.
