Huvitz HRK-1 Auto Ref/ Keratometer


Huvitz HRK-1 Auto Ref/ Keratometer

Category :Auto Refractor / Keratometer
Brand :Huvitz


Smart Assembly Moving Control (SAMC) Tech

Considering the refractive error of the patient, the measurement ring is projected on the retina, and is adjusted automatically by Smart Assembly Moving to secure a stable signal. HRK improves the effect of uneven light reflection in normal and cataract eyes with the results being more accurate refractive power REF data.

Quick Virtual Aiming Dot Function

The Aiming Dot quickly guides you to easily find the patient’s visual apex from any position for fast alignment. Reliable refractive power REF data is then automatically obtained.

Immediate Color View Mode

Full color camera and white LED light is used for color display, overall condition monitoring, contact lens fitting and prescription.

Contact Lens fitting Assistance Guide

Image processing, using a fluorescence solution and yellow filter, automatically determines the fitting state.
