ARGO PD-180

PD180, PD Meter is a precion optical instrument used to measure distance between pupils in the process of optometry for spectacles

This device is a scientifíc and reasonable design, consisting of measurement system, optical system, ESS and Computer software system into a whole.

Using mechanical hairspring to level at the reflecting point of human cornea to realize the consecutive measurement. It features direct point-sampling and high accuracy of orientation.
Adopting high-precision line-shaped sensors, advanced intellectualizedelectronic systems and digital display which allow the testing results more visible, legible and accurate.
The design of LED lamp-house and low-power consumption ensurcthe prolonged Service life of batteries.
It offers thc+2.00D compcnsation for the visual dcgrec.
The brightness of LED lamp-house is adjustable.
