    Canton PD Meter

    Price:  $0.00

     

    Uses

     

    PD Meter is a precision optical instrument used to measure distance between human pupils in the process of optometry for fitting spectacles.

     

    Characteristics

     

    This device is designed in a scientific and reasonable way, integrating technologies on mechanical hairspring orientation
    measurement system, optical system, ESS and microcomputer into a whole. Using mechanical hairspring to level at the reflecting point of human cornea to realize the consecutive measurement. It features directness of point-sampling and high accuracy of orientation.

     

    Adopting line-shaped sensors of high definition ,advanced intellectualized electronic systems and digital display which allow the
    testing results more visible, legible and accurate.    

     

    LED lamp-house and a design of low-power consumption ensure the prolonged service life of batteries.It can realize the measurement of conversion between the PD and the distance of glasses and eyes.
    It offers the +2.0D compensation for the degree of eyesight. The brightness of LED lamp-house is adjustable.


    Features:

    1. Accuracy self-check function
    2. VD measurement function
    3. It features consecutive measurement, direct point-sampling and high accuracy of orientation, with mechanical hairspring being used to level at the reflecting point of human cornea
    4. Adopting line-shaped sensors of high definition advanced intellectualized electronic systems and digital display which allow the testing results more visible, legible and accurate.
    5. The design of LED lamp-house and low-power consumption makes the battery life prolonged
    6. The brightness of LED is adjustable
    7. +2.00D compensation for the degree of eyesight is available
