Optical Pupillary Distance Meter with Memory Function, LED Display and Diopter Compensation

When measuring, ensure the environment is well-lit. Do not move the device to avoid large errors. Remove the battery when the instrument is not in use for an extended period. Position the eyes of the two people at the same level to enhance measurement accuracy. When measuring the distance between the two eyes, keep the device steady and confirm both left and right eyes are aligned with the vertical line in the field of view simultaneously.

The device does not include batteries. It is white in color and made of metal. The item weighs 1.4 pounds and the package dimensions are 0.08 x 8.62 x 3.94 inches. The material is plastic. The batteries required are alkaline, and the device is waterproof with a CE rating.

【SIMPLE OPERATION & EASY TO USE】 To operate the PD meter, turn the power button on and off. The pupillometer will automatically power off after use and retain the memory to extend battery life. This system does not induce parallax. The nose and forehead support helps stabilize the instrument against the patient's face, making it accurate and easy to use. (Please provide your own 2 AA batteries, as they are not included in the package).

【MEASURING ACCURACY ±0.1/0.2/0.5MM ADJUSTABLE】 Depending on the accuracy requirements of the actual glasses, the measurement step increment, or accuracy, can be set, instead of being fixed at 0.5mm. This makes the measurement results from the Huanyu PD measuring tool more reliable.

【POWER METHOD】 The device requires 2 AA batteries. Due to relevant policies, the batteries are NOT INCLUDED, please understand. Press and hold the power button for 3 seconds to turn it on (remember to press and hold for 2 seconds).

【30CM-∞ ADJUSTABLE VISION DISTANCE】 The 9A pupil distance meter can be set to various vision distance gears, including 30cm, 40cm, 50cm, 1m, 2m, and infinity. This function is used to measure the interpupillary distance of patients at different sight distances.

【MULTIFUNCTIONAL】 Our pupillometer also has the following features: automatic shutdown after 3 minutes of inactivity; automatic memory of the last value (no machine operation during this period); adjustable LED energy-saving lamp brightness from 0.5 to 3.0 degrees; and +2.00d visual acuity compensation.
