I edited your spelling from 'kentos ring' to 'keto ring'. If you search the forum or web for ketos ring you will find better information.

Is more easy that you buy the Ring AS5282, is the same that Ketos Ring but wih more sensibility the diference is the annealing. Is difficult to find the ketos ring, and to make it more; many vendors say they sell the ketos ring, but really is the as5282 ring.

Best regards.
