Product Description
The Refurbished/Pre-owned Topcon KR-8800 Auto Refractor is loaded with new features with proven consistent and accurate results. Now available at a reduced price, the KR-8800 delivers precise accurate objective refraction data with the Topcon exclusive Rotary Prism Technology.
Rather than single-measurement points like other auto-refractors, the Rotary Prism covers a wider field, ensuring the most reliable objective refraction data.
The KR-8800 offers an all-new color LCD monitor, reduced measurement time, a small 2mm minimum pupil requirement, pupil/cornea diameter measurements, PD measurement, an infra-red reflex feature to monitor developing opacity, and USB and RS-232 connections for enhanced and faster data transfer.
