PD-400 Digital PD Meter

The PD-400 digital PD meter features a high-definition camera that significantly reduces visual errors typically caused by monocular observation by the optometrist. It allows simultaneous adjustment of both eyes' pupillary distance (PD), enhancing measurement efficiency. For energy conservation, the device automatically enters sleep mode after 30 seconds of inactivity and powers off completely after 4 minutes without operation.

Redefine the way of measuring the PD

The PD-400 digital PD meter is equipped with a high-definition camera that ensures precise measurements by eliminating errors often caused by manual, monocular observation. It allows for the simultaneous adjustment of both eyes' pupillary distance, significantly improving measurement speed and workflow efficiency.

Designed with convenience and hygiene in mind, the PD-400 operates without requiring close contact between the practitioner and the patient. Simply place the device against the patient’s forehead, and it's ready to measure—no need for the traditional viewing window.

To optimize energy usage, the device automatically enters sleep mode after 30 seconds of inactivity and powers off after 4 minutes without use.

Longer working hours

The high-capacity 3000mAh rechargeable battery ensures extended operation. Once fully charged, the device can run continuously for up to 10 days, based on testing with 15–20 measurements per day.
