RM-850 Auto Refractometer, RK-850K Auto Ref Keratometer

RK-850K and RM-850 auto reratometers are precise and objective eyesight test device for ophthalmologists or optometrists. There are two models, RM-850 auto refractometer, and RK-850K auto ref keratometer with keratometer test function. These auto refractometers are mainly used to measure patient’s diopter, including sphere power, cylinder power, optical axis, pupil distance and corneal curvature, in order to provide reference data for eyeglass fitting, eye diseases diagnosis and treatment. They have unique optical system, accurate imaging analyzing and processing technology.

The measurement result can be displayed on screen, printed out on paper, or transferred to auto phoroptor (with RS232 interface).
