POTEC PDR-7000 Digital Refractor | Subjective Refraction System

Description

Supply Dual Cross Cylinder Lens: Dual cross cylinder lens makes more accurate and easy for astigmatism tests.

Near Sight Test: Various acuity charts enable to perform near sight test easily.

Practical Viewing Angle: Enable the practical test with the viewing angle, 40 degree.

PD Adjustment and Fast Lens Rotation: Independent Left / Right PD adjustment enhances the reliability of test results using an eye chart by bright illumination of LED light. Fast lens rotation speed minimizes eye fatigue.

Useful and Convenient Vision Test Features: By useful vision test function, it is easy to explain to patients and make them understand about various refractive error and diseased as well as near visual acuity with near eye chart and auxiliary eye
chart, and eye chart can be selected depending on user’s taste and the purpose.

Providing Tilting & Swivel Monitor: Regardless of the position of the patient and the optometrist, the screen can be
shared any angle and direction.

Provide Large Screen and Convenient Touch Screen Display: As progress of diagnose and gures are expressed in an 10.4 inch wide screen with intuitive interface and various colors, it is easy to understand and aware of the test contents, and due to adopting
touch-screen, optometry progress can be progressed easily even if optometrists do not familiar with the operation.

Wireless Networking (Optional): It can be connected to PRK-9000, PLC-9000 and PLM-8000 via Wi-Fi.
