Topcon KR-8900 Auto Kerato-Refractometer

Topcon KR-8900 Auto Kerato-Refractometer

The Topcon KR-8900 auto kerato-refractometer measures refractive error and corneal curvature. It combines automated refractometry and keratometry in one ophthalmic instrument. As a result, eye care professionals can use this type of equipment to obtain objective measurements during vision examinations.

This used Topcon KR-8900 is available from Sapas Lab Equipment as medical surplus. The unit powers on, and its color LCD illuminates and loads the internal operating software to the “SETTING MENU.” However, this initial test does not confirm that the instrument measures accurately or performs all its functions.

Topcon KR-8900 Features and Measurement Capabilities

• Automated refractometry and keratometry in one instrument.
• Rotary prism measurement system.
• Minimum measurable pupil diameter of 2.0 mm.
• Motorized chin rest.
• USB and RS-232C interfaces.

Unit Condition and Testing Limitations

The unit is used medical surplus. Its exterior casing, joystick assembly, and patient chin and forehead rests show minor signs of previous clinical use and are reported to be in good physical condition.

Our testing confirmed that the instrument powers on, illuminates its color display, and loads the internal software to the setting menu. However, we have not verified measurement accuracy, calibration, or full operational performance. Therefore, buyers should expect to evaluate the instrument further and arrange any necessary service, preventive maintenance, or calibration before clinical use.

Please consider these testing limitations when evaluating the unit for your application. Contact Sapas Lab Equipment if you need clarification about the reported condition or the product photographs.
