Refractoin & Keratometry Measurement
HRK-9000 provides an extensive dioptric measurement range (-25D to +22D), and the radius of curvature for keratometry is 5.0mm to 10.2mm. Easy alignment and friendly operation allows you to measure the refraction and keratometry in sequence, and the results can be validated immediately. Owing to its easy alignment and friendly operation you can measure the refraction and keratometry in a sequence, the results can be checked all at once.TFT-LCD with Touch Screen
By adopting high resolution VGA TFT-LCD with Touch Screen function, we virtually removed all input keys except the measurement button on the Joystick and Chinrest control switches. Tests are performed rapidly and conveniently by simply pressing a button or the icon indicated on the screen.IOL Measurement
When refraction results in an error reading due to an intraocular lens or cataract the measurement can be performed with the IOL icon switched 'ON'Motorized Chinrest
The chinrest is motorized with the use of a switch conveniently positioned for the operator. This makes for simple adjustment of the chinrest from patient to patient.Data Transfer
Data can be transferred to external devices (personal computer, etc.) via an RS-232 interface. A USB interface is also provided for future compatibility.
