Brand: Huanyu

Color: Blue

Features:

• 【RECOMMEND LY-9AT】 This digital interpupillary distance meter features direct point-sampling and high accuracy of orientation. Compared to LY-9C, this one is more accurate in measuring monocular pupillary distance and has three self-setting functions The design principle is more advanced and reliable, which is our original patented model! No imitations!
• 【MEASURING ACCURACY】±0.1/0.2/0.5mm is adjustable: According to the accuracy requirements of the actual glasses, set the measurement step increment, that is, accuracy, instead of fixed 0.5mm, the measurement results are more reliable.
• 【ADJUSTABLE LIGHT BOX BRIGHTNESS】0.5-3.0 DEGREES: In order to adapt to different measurement environments and patients’ vision conditions, adjust the light box brightness to make the blue aperture in the patient window clear and bright, and keep the pupil position during the measurement.
• 【ADJUSTABLE AUTOMATIC SHUTDOWN TIME】 30s-3min adjustable：Equipped with a power button, press the button to turn on / off, and can also set the automatic shutdown time, saving electricity. As long as the slider is not moved, the last measurement result is saved after auto power off, and the data can be read again after power on.
