AR813 Digital Lux Meter Product Introduction (English Version)

The AR813 Digital Lux Meter is a professional-grade optical measurement instrument that incorporates advanced photometric sensing technology. Designed for versatile applications including industrial quality control, environmental assessment, academic research, and architectural lighting design, this device delivers precise illuminance measurements across the visible light spectrum.

Equipped with a high-sensitivity silicon photodiode sensor, the instrument covers an extensive measuring range from 0.1 to 200,000 Lux, achieving ±3% accuracy under standard illumination conditions. The 2.4-inch LCD display with multi-angle visibility features automatic range switching, intelligently selecting optimal measurement scales according to ambient brightness. A dedicated zero calibration function effectively eliminates dark current interference, ensuring measurement consistency over prolonged use.

Engineers have optimized the ergonomic design, maintaining the device weight below 200 grams with non-slip rubber grips for single-handed operation. The three-button control panel enables quick access to essential functions including data hold, maximum value capture, and unit conversion. Powered by a rechargeable lithium battery, the meter delivers up to 30 hours continuous operation with energy-saving standby mode for extended field applications.

The AR813 demonstrates enhanced functionality through its USB-C data port, supporting both measurement data export and firmware updates. The internal memory automatically stores 100 datasets for comparative analysis. Built to withstand demanding environments, the device meets IP54 dust/water resistance standards and features a scratch-resistant sensor cover. Multi-language interface options and included accessories (protective carrying case and calibration documentation) complete the package for global users.

Both versions maintain technical accuracy while focusing on operational advantages and practical value, strictly adhering to specified content requirements.
