Realization of Simple and Highly Cost-effective Refkerato Functions Refractometry: Simple handling of the fine adjustment and measurement by yourself. Fogging is applied automatically for each measurement for more accurate results. Keratometry: Short consecutive measurements and time provide reliable data. Measurements at Ø3.0mm (R = 8.0mm) give you enough information for contact lens fitting. Diameter Measurement of Cornea and Pupil: Easy measurement by moving the two cursors on the display to the boundaries of Cornea or Pupil. Language Selection: ARKM-150 has a Multi-language function. You can select your required language from “English”, “Japanese”, “German”, “Chinese”, “Spanish”, “Spanish Latin America”, “Italian”, “Portuguese”, “French” and “Russian”.
