The Justice AR-860-A / ARK-860 Auto Ref Keratometer is designed for ophthalmology and optometry practices requiring automated refractive and keratometry measurements. The instrument uses an embedded microprocessor and fast image processing technology to support quick measurement and data acquisition.
The auto-reading function allows measurements to be taken automatically once satisfactory focus and alignment are achieved. The system also includes an auto fog chart to support refractive measurement and provides automatic pupil distance measurement.
A choice of multiple vertex distance settings allows measurements to be performed according to the required prescription parameters. The instrument also includes an IOL mode and a soft-lock system for convenient operation.
The 8-inch color TFT LCD touch screen provides clear display and direct control of functions. Measurement results can be printed using the built-in thermal line printer.
The AR-860-A / ARK-860 supports measurement of sphere, cylinder, axis, pupil distance, and minimum pupil size. The keratometry functions include corneal radius of curvature, corneal power, and corneal astigmatism measurements. Its compact design and automated functions make it suitable for ophthalmic clinics, optometry practices, and eye diagnostic environments.
