Factory Supply CE Certified SY-V004K Portable Refractometer with Keratometer Function

Basically combines refractometry and keratometry in one portable unit—saves you form buying two separate machines, and we've found that most clinics using it cut exam time by about 40% once they're trained. 2. The 8-inch TFT touch screen is adjustable and bright enough that you won't squint under harsh lighting, though the motorized chin rest is what actually saves time during patient positioning, and it's a 22kg unit so it's not exactly lightweight but still manageable for a mobile setup. 3. It measures spherical power from -20.00D to +20.00D and cylindrical up to +10.00D with corneal curvature from 5.0mm to 10.0mm radius—better than many benchtop models for this price range, and the Hartmann principle light path gives you clear imaging in under half a second. 4. We usually have stock within 20 days or so, but check lead time if you need more than 10 units because production fluctuates, and MOQ is typically 1 unit with CE and ISO13485 certs included. 5. Also, it stores only 10 measurements onboard, so you'll want to export data regularly if you're running high volume—though the 57mm thermal printer is handy for quick printouts right there in teh exam room. 6. It's not ideal for pediatric patients who can't sit still during the 0.5-second capture, but for routine adult exams in optometry clinics or mobile screening, most buyers go with this model over the cheaper alternatives because the measurement repeatability is tighter.
