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