Nidek HandyRef-K Handheld Refractometer is the mobile solution for accurate refraction and keratometry measurements anytime and anyplace. The HandyRef-K are lightweight and have excellent weight distribution. Its compact design makes it effortless to hold, equilibrium, and use. New full graphics 3.5-inch color LCD is 40% bigger than the prior model. Clear display layout and intuitive icons provide high user-friendliness. The measurement data of 50 patients (100 eyes) can be saved in the main body memory. For inexperienced patients like children, recently added melody role can ease individual’s anxiety and draw attention. Data can be transferred quickly and easily to PC and NIDEK RT. Two sorts of fixation target (scenery or children) are readily available. By employing the mobile stand, the HandyRef-K and Nidek HandyRef may be used as a desktop device.

The HandyRef-K adopted an excellent new measurement method; “SynchroScan Technology”. Measurements begin when the alignment begins and locks in the information if alignment gets optimal as a dimension value. The qualities of this HandyRef-K permit simple, accurate dimensions while maintaining efficiency.
