PD METER - FPD-07

SummaryThe PD Meter is a digital precision optical instrument used to measure distancebetween human pupils in the process of optometry for fitting spectacles.Detailed Product Description1, 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 poweroff 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.ParameterEffective range of measurementbinocular pupillary distance 45-80mmleft or right pupillary distance 22.5-40mmIndication error ≤0.5mmDistance of targent 30cm ~ ∞Electric Voltage DC 4.5V(3pcs 5# AA battery)Power 10WWeight 0.6kgVolume 21.5(L)x15(w)x50(H)cmUsesPD Meter is a digital precision optical instrument used to measure distance between human pupils in the process of optometry.CharacteristicsThis device is designed in a scientific and reasonable way, integrating technologies on optics, microelectronics.MAIN TECHNICAL INDEXES1,Range of data displayBinocular pupillary distance 44~83mmLeft or right pupillary distance 22~41.5mm2,Effective range of measurementBinocular pupillary distance 45~82mmLeft or right pupillary distance 22.5~41mm3,Indication error≤0.5mm4,Rounding error≤0.5mm5,Distance of target30cm~∞6,Power sourceVoltage DC 6VSpecification AA batteryQuantity 4 pieces7,Time for automatic shut-off1 and a half minutes after stopping operation8,Overall dimensions219mm(L)×169mm(W)×86mm(H)9,Weight0.7kg
