The JUSTICE AR-800A / ARK-800A Auto Refractometer & Keratometer is designed to support efficient and accurate eye examination and objective refraction measurement in optical practices, eye clinics, and ophthalmology centres.
Powered by an embedded microprocessor and fast image processing technology, the instrument delivers quick measurements while helping streamline the examination workflow. Its auto-reading function automatically captures measurements once satisfactory focus and alignment are achieved, reducing manual operation.
The system features a 5.7-inch TFT LCD display for clear viewing and an auto fogging chart to support comfortable and reliable refraction measurements. It also offers automatic pupil distance (PD) measurement, selectable vertex distance settings, and the ability to measure small pupils down to 2.2 mm.
The AR-800A is designed for objective refractive measurements, while the ARK-800A Auto Ref/Keratometer additionally provides corneal measurement capabilities. A built-in thermal printer allows convenient printing of measurement results.
With its compact design and fast measurement performance, the JUSTICE AR-800A / ARK-800A is suitable for ophthalmology clinics, optometry practices, eye hospitals, and optical diagnostic environments.
