VRK -2400

helps accurate examination

more comfortably.

VRK-2400 supports various and fast examination mode to diagnose

Refractometry and various convenient function.

Variable examination mode

VRK-2400 has Refractometry function (REF Mode),

Keratometry function (KER Mode),

Keratometry&Refractometryfunction (K/RMode),

contact lens based curve function (CLBC Mode),

Auto Start and so on.


By freeze function, diameter of cornea, pupil

or hard contact lens can be measured.

Wide range of measurement

VRK-2400 provides range of refraction for

SPH from -25D to +22D, and radius of

curvature from 5.0mm to 10.2mm

Sophisticated and

modern design

With the black and white color, it can be assimilate at your refraction room.
