【English Version】
The DT8809 Lux Meter is a professional-grade light intensity measuring instrument featuring wide-range detection capability from 0.1 to 400,000 Lux. Equipped with auto-ranging technology, this device intelligently selects optimal measurement modes for various environments ranging from dim interiors to intense lighting conditions.

The core innovation lies in its high-sensitivity photoelectric sensor coupled with a multi-layer optical filter system, which effectively minimizes infrared/ultraviolet interference while maintaining measurement accuracy within the visible spectrum. The data hold function allows instant value locking for reliable recording in dynamic environments, while the relative value mode enables differential lighting analysis for specialized applications.

Ergonomically designed with a 200g lightweight body and anti-slip casing, the meter ensures comfortable single-hand operation. The 3.5-inch dual-backlit LCD display provides clear visibility under various lighting conditions, with a night-friendly low-light mode. Built-in memory stores up to 200 data sets, supported by USB-C connectivity for efficient data transfer.

This device serves multiple industries including industrial inspection, environmental monitoring, agricultural greenhouse management, and architectural lighting design. It proves invaluable for film lighting adjustment, plant growth light optimization, and laboratory research applications. The shock-resistant carrying case ensures component protection across operating temperatures from -10℃ to 50℃.
