Compared with mechanical PD gauges, the YJ-400's electrical measurement and 4.3-inch LCD readout provide a self-contained digital workflow, and its CE listing supports buyer confidence without requiring separate certification validation. Buyers who prioritize procurement efficiency will also note that the YJ-400 is listed as a Class II instrument under the GB15979-2002 safety standard and carries CE marking in the quality certification field—data points often required by institutional procurement checklists.
Installation & Operation Notes
Henan Forever Medical Co., Ltd. supplies the YJ-400 as a single item with package dimensions of 34 x 42 x 35 cm and gross weight of 34.000 kg. This compact footprint allows the unit to be set up at an intake desk, pre-test room, or dispensing table without specialized mounting hardware listed in the product data. The packaged gross weight should be accounted for in shipping and receiving workflows, especially for multi-unit orders.
- Electrical setup: The device uses electricity with DC 3V specification and a 3000 mAh battery capacity, enabling cordless operation during patient flow.
- Measurement range verification: Confirm the binocular 45–82 mm and monocular 22.5–41 mm ranges before each session; the instrument's switching gear position allows near and far measurement without reconfiguration beyond the specified modes.
- Near/far switching: The measuring gear position is specified as switching from 30 cm to infinity, so operators can alternate between reading and distance PD capture according to the fitting task.
- After-sale assistance: Online technical support is available from the manufacturer, and the unit is covered by a 1-year warranty.
Because the product data does not include step-by-step calibration procedures, buyers should request final installation guidance from Henan Forever Medical Co., Ltd. before first patient use. The China origin listing is paired with online technical support, which can assist international buyers with remote setup questions.
Applications
In the Health & Medicine category, pupil distance measurement is a foundational step in producing accurately centered spectacle lenses. The YJ-400 addresses this need in optical shops, hospital ophthalmology departments, and vision care practices where staff need rapid, repeatable PD values.
The 4.3-inch LCD screen and electrical measurement design help standardize readings across multiple operators and locations, which is particularly relevant for chain optical retailers and multi-room clinics that require consistent device behavior. The single-item selling unit and 34 x 42 x 35 cm package size also simplify inventory replenishment for branch networks. Beyond static clinic use, the battery capacity and electrical operation allow the device to be moved between pre-test and dispensing areas without dependence on fixed outlets, which supports high-volume optical retail environments.
