Nowadays, automatic refractometry is a usual practice for every ophthalmologist and optometrist. With Humphrey Zeiss 597, a specialist will never get bored with his daily routine duties. This auto refractometer distinguishes with its ease of use, plain but attractive design, accurate measurement instruments, etc.
The functionality of the tool is improved with additional features such as keratometry and visual acuity study. The Humphrey auto refractometer price is affordable for various organizations — just 3,600€.
- New control unit with integrated joystick – can be optionally positioned at 90 ° and 180 °. Ideal for adaptation to existing space conditions and the special requirements of the examiner.
- Fully automatic electronic self-centering – the measurement always takes place exactly on the visual axis and with the correct corneal vertex distance. Of course, even with troubled subjects and children. Even inexperienced examiners can achieve the very best measurements with the new refractometer, operating errors are virtually eliminated.
- Programmed sequence of refraction – automatic centering, measurement of both eyes and printout of results.
- One measurement is sufficient – multiple measurements are not necessary due to the Foucault cutting principle system.
- Correction success is immediately visible, an integrated lens system automatically sets the determined values. The visual acuity with this correction can also be queried.
