Model: ARK-7800
ARK-7800 auto ref keratometer is an eyesight measurement machine for optical store, ophthalmic clinic, or hospital. It is mainly used for testing sphere and cylinder refractive errors, and corneal curvature. It uses a new optical system with Hartmann imaging analysis to deliver stable and accurate refraction results.
The system features a movable TFT touch screen, motorized chin rest, and auto tracking and focusing for easy operation. A built-in printer with automatic paper cutting supports quick output of test results in daily clinical use.
1°–180° Axis, One key lock function, convenient and practical.
7.0 inchs touch screen, angel adjustable, provide operator with comfortable viewing angle both when sit or stand.
