Auto Refractor Autorefractor Refractometer Keratometry 7" TFT LCD Screen CE FDA Certification

Product Description This product is designed for measuring the refractive error of the human eye (including myopia, hyperopia, astigmatism, and optical axis), providing data for ophthalmic diagnoses and glasses prescriptions.  This product ships from China. Tilting 7" TFT touch screen: adjustable 0 to 85° Followed-up colorful fogging chart system Built-in thermal printer RS-232 interface Equipped with Keratometer: REF, KER and R&K Joystick: control the machine to move forward/backward, left/right, up/down Net Weight: 32.41 lb/14.7kg Product Size: 9.05"x18.90"x16.93"/23x48x43 cm Dimension & Packing List Item Quantity Item Quantity Refractor X 1 User’s manual X 1 Print paper X 5 Dust cover X 1 Power cord X 1 Fuse X 2 Hexagonal wrench X 1 Test-eye X 1 Product Details Tilting 7" TFT LCD Screen: The screen angle can be adjusted from 0 to 85 degrees. The large touch screen displays icons and menus clearly for easy navigation. Equipped with Keratometer: You can select from three measurement modes via the screen keys: REF, KER, and R&K. This feature allows for both eye diopter and corneal curvature measurement. High precision: Using rotating prism and a double telecentric optical system, along with the follow-up colorful fogging chart system, this machine delivers exceptional accuracy and reliability. Built-In Thermal Printer: The printed results are clear and precise. Data for the left and right eye can be recorded separately up to 10 times. The printer paper is easily replaceable. Measurement Methods : The system can be set to manual or automatic measurements using the screen keys. A tracking mode automatically adjusts the measurement focus via automatic sensing and a 3D mobile device. Simple and Convenient Operation : Control the machine easily with the touch screen, or use the shortcut keys and joystick to move the machine forward/backward, left/right, or up/down. /* General Styling */ .product-details { display: flex; flex-wrap: wrap; gap: 30px; justify-content: space-between; margin-bottom: 50px; } .product-detail-item { flex: 1 1 30%; /* Default to 3 items per row (30% width) */ text-align: center; transition: transform 0.3s ease-in-out; margin-bottom: 30px; } .product-detail-item:hover { transform: translateY(-10px); } .product-detail-item img { max-width: 72%; /* Make images smaller */ height: auto; border-radius: 15px; box-shadow: 0 6px 25px rgba(0, 0, 0, 0.15); } .product-detail-item p { font-size: 14px; color: #666; margin-top: 15px; } /* Responsive Design */ @media (max-width: 768px) { .product-detail-item { flex: 1 1 48%; /* On mobile, each item takes up about 48% of the width */ } } @media (max-width: 480px) { .product-detail-item { flex: 1 1 100%; /* On very small screens, items will stack vertically */ } } operation Guide Release the Limit Screw Remove the plastic cap and unscrew with a hex wrench. Move the instrument by hand (front, back, left, right). Lock or unlock the machine by flipping the moving lock. Fuse Replacement Turn off the system and disconnect the power. Use a flathead screwdriver to remove the fuse holder and replace the fuse. Reconnect the power cord. Test-Eye Calibration Compare the test-eye values (SPH: -5.00D, CYL: 0.00D at VD=12mm) with the measurement. Difference should be within ±0.25D. Recalibrate if needed.

Recalibrate if necessary. Clean Environment: Use the device in a dry, clean area. Avoid exposure to dust, moisture, or direct sunlight. Handle with Care: Avoid rough handling or sudden impacts to prevent damage to the device's sensitive components. Power Off After Use: Always turn off the device and disconnect the power supply after use to prolong its lifespan. Regular Maintenance: Clean the device regularly with a soft cloth, especially the touchscreen and lenses, and replace fuses if needed. /* General Styling */ .instruction-container { padding: 40px 20px; background-color: #f9f9f9; border-radius: 10px; box-shadow: 0 2px 10px rgba(0, 0, 0, 0.1); margin-bottom: 50px; } .instruction-content { display: flex; justify-content: space-between; flex-wrap: wrap; gap: 20px; } .video-container { flex: 1 1 48%; border-radius: 10px; overflow: hidden; box-shadow: 0 6px 25px rgba(0, 0, 0, 0.15); } .text-container { flex: 1 1 48%; padding-left: 20px; text-align: left; color: #333; } .text-container h3 { font-size: 22px; margin-bottom: 15px; color: #0073e6; } .text-container p { font-size: 16px; line-height: 1.6; margin-bottom: 15px; color: #666; } .text-container p strong { color: #333; } /* Responsive Design */ @media (max-width: 768px) { .instruction-content { flex-direction: column; /* Stack video and text on top of each other */ align-items: center; } .video-container, .text-container { flex: 1 1 100%; /* Each container takes up 100% of the width on small screens */ padding-left: 0; padding-right: 0; } .text-container { text-align: center; /* Center text on mobile */ } } Specifications Refractometer Sphere (SPH) -20 ~ +20 m-1 (VD=12 mm); 0.12/0.25 m-1 step Cylinder (CYL) -8 ~ +8 m-1; 0.12/0.25 m-1 step Axis 0 ~ 180°; 1° step Pupil Distance(PD) 45 ~ 88 mm; 1 mm step Vertex Distance(VD) 0 mm, 12 mm, 13.75 mm Min.
