The PDM Digital Pupilometer is produced with the quality you expect from Reichert Instruments, yet it is one of the most affordable digital P.D. meters available.
Obtaining accurate interpupillary measurements with the PDM is easy. Operators simply align the measuring lines to the Purkinje images on the patient's corneas. Measurement data can be obtained for a single eye, or both eyes, and results are accurate within 0.5mm. Interpupillary distance for a range of focusing points can be obtained by selecting the appropriate focus distance on the circular dial. The PDM's LCD displays measurement data in clear, easy-to-read format.
This new Reichert PD Meter is ergonomically designed to be easy to hold and measure at the same time, while the forehead bar fits the patient's forehead comfortably. The PDM automatically switches off after one minute of inactivity to ensure long battery life. In addition, the patient fixation target is illuminated by a low-power LED, further extending battery life and ensuring virtually maintenance-free operation.
