Digital Pupil Distance Meter Optical PD Meter Pupilometer Measuring Tool
This PD meter is a scientific and perfect design, consisting of measurement system, optical system, ESS and computer software system. A precision optical instrument used to measure distance between human pupils in the process of optometry for fitting spectacles.
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 intellectualized electronic system and digital display which allow the testing results more visible, legible and accurate.
The design of LED light source and low power consumption, longer service life of the battery.
LED light source, time of auto power off could be adjustable. There is a +2.00D lens under measuring window to make a visual compensation.
Binocular distance:45-82mm
Absolute value of indicated error: ≤0.5mm
Distance of testing target: 30cm-∞
Power supply: Two AA battery
Weight: 0.6kg
Product Description:
1, It employs precise optical structure, the line of light is very clear and precise measurement. The measurement results are displayed digitally, and the left eye and right eye measuring values are displayed separately.
2, Simple and rapid measuring operation, and free operation of the direct PD adjustment lever are possible. Combining with the adjustable viewing distance selecting lever for measuring all kind of the viewing distances, the PD measurement is simple and precise.
3, When the measuring operation is finished, the auto power off and memory function, enable to save the power and not to lose the data.
4, It can also be used in monocular the left eye and right eye separately.
