A-10 Concentricity Gage is comprised of three main components for assembly. #1） selection of standard or precison accuracy, #2） selection of main rollers, #3） select an indicator（s） and/or other accessories. There are two classifications calibrated and directly traceable to （N.I.S.T.）, Standard Black Gages are guaranteed to be better than ≤ 4µm （.00016"） accuracy. Precision Gold Gages are guaranteed better than ≤ 2µm （.00008”） accuracy.
