auto refractor keratometer
(ARK-800)
Technical Data
The first internal set auto refractometer/keratometer. It can measure not only refractometry but also keratometry. Color TFT LED monitor special font design makes operation convenitent. The foggy method of the eye fixation targer makes examinee's eye comfortable and enables to get more accuate measurement data.
