03. Auto Refractometer FRE-03

Keratometry and refractometer mode select: 1. Auto refractometer 2. Auto refractomere with Keratometer

1.Use the ARM processor and the latest domestic image processing, the system is fast and the image is clear.
2.Japan’s mature optical path system, humanized automatic mist measurement process, to reduce the error caused by adjustment,
3.more precise measurements.
4. Light rack with integral casting , CNC machining, measuring system is more stable , good consistency.
5. Data transmission with computerized vision tester, improved efficiency of online.
6. Motorized chinrest
7. Auto detachment printer
8. Auto tracking optical system
9. 5.7’ tiltable color LCD
