Unique Functions of the ERK-5400 Auto Refractor/Keratometer? Auto Refractor/Keratometer ? Enhanced Measurement of Corneal Diameters ? Wide Dioptric Measurement Range ? Focusing Control Software ? Retro Illumination Mode ? Temperature Control Chip ? Compact & Modern Design ? Communication Interface ? 7 Inch Color LCD, Touch Screen Monitor ? Internal Thermal printer ? Comfort and Easy Operation ? Easy Network Capability ? Backed by an Industry Leading 2-years Warranty! ? Auto Refractor/Keratometer The ERK-5400 instantly reports the patient's assessed eye power by combining the Auto Refractor/Keratometer functions into this one sharp instrument, making measurement a snap. This determines the refractive and keratometric properties of the human eye to assist eye care professionals in the process of prescribing corrective eyeglasses and contact lenses. ? Enhanced Measurement of Corneal Diameters The corneal diameter and base curve of contact lenses can be measured with this one instrument. Thus, measurements of eye and prescriptions for glasses and contact lenses can be made more efficiently. ? Wide Dioptric Measurement Range Because the ERK-5400 covers a wide measurement range from -25D to +22D, even an examinee with strong myopia can be measured. ? Focusing Control Software In the event that the operator miss focused while measuring the patient's eyes, the software automatically registers the data as if it were in focused producing the correct measurement data result. ? Retro Illumination Mode In ILLUM mode what illuminate to pupil, can be observe the condition of cataract & a scar of contact lens through screen. ? Precise Temperature Sensors Temperature Control Chip Temperature Control chip is a temperature sensor for precision that detects the internal temperature with each measurement which ensures the precise data. ? Advantage of this Chip Every users will get an exact measurement data regardless of the internal temperature. This will ensure stability, repeatability, and highly accurate measurement data. ? Compact & Modern Design European Style was created to maintain a sleek 2 piece casing design that make for simple reconditioning while adding sharpness for any practice. ? Communication Interface A data communication available among relevant diagnosis devices by RS-232 and Video terminal technology such as a connection to computer, T.V monitor, etc. ? 7 Inch Colored Liquid Crystal Display All measurement result data within the various functional programs are displayed in color through this clear and precise 7inch screen. ? Internal Thermal printer Automatic printer with ample paper supplement, conveniently located for ease operation. ? Comfort and Easy Operation Mechanically the main body moves smoothly from right to left, forward to backward applying the improved design of base sliding structure. ? Aiming target A clear and fine aiming target design increases measurement data accuracy. ? Easy Network Capability This instrument is designed to connect to additional diagnostic equipment.
