Used - Good TOPCON KR-8800

• The price is negotiable

• Serial number: 4113580

• Power supply: 100-240V / 50-60Hz / 75VA

• Year of production: 2006

• Provides precise, accurate, objective refraction data with Topcon's Rotary Prism technology

• Instead of single measurement points like other autorefractors, the Rotary Prism covers a wider field, providing the most reliable objective refraction data

• It has a keratometry function - measurement of the curvature of the anterior surface of the cornea

• Motorized optical head that monitors the patient's vision and adjusts itself

• 5” color LCD monitor

• Automatic measurement mode

• Reduced measurement time, minimum pupil diameter requirement of 2 mm, pupil/corneal diameter measurements, pupil divergence (PD) measurement, infrared reflectance function to monitor developing opacity, and USB and RS-232 connections for improved and faster data transfer

• It has a built-in thermal printer with paper diameter: 5.5 cm

• Manual adjustment of the chin rest within a range of 7 cm
