Audited Supplier HC-Q027 Top Quality Ophthalmic equipment digital handheld and portable auto Keratometer
Features for HC-Q027 Top Quality Ophthalmic equipment digital handheld and portable auto Keratometer:
Electronic Keratometer is made of three parts, including light source, Measurement of optical system and display system. To focus, the operator need make the unit up and down, back and forth. When the focusing condition is met, When all the four image points are in the center of the screen, instrument will calculate automatically the curvature radius and diopter and display the result on the screen.
