3nh YL4668 Spectrophotometer and Color Meter

3nh YL4668 Spectrophotometer and Color Meter

The 3nh YL4668 spectrophotometer is a color measurement instrument utilizing the standard d/8 geometry (diffuse illumination, 8-degree viewing angle, SCI Specular Component Included). It executes non-contact measurements between the optical sensor probe and the target sample, enabling precise non-contact color quantification for liquids, sauces, powders, and other challenging substances. The streamlined probe architecture allows this product to be integrated at any junction along automated production lines for live color measurement and continuous color quality control. It is widely implemented across cosmetics, fruits and vegetables, food hygiene inspection, plastic electronics, paint and inks, commercial printing, ceramics, and other core industrial sectors. Additionally, it is capable of measuring fluorescent samples. Its unique and innovative design not only delivers non-contact, non-destructive measurement solutions directly from the active production line but also guarantees exceptionally stable and high-precision data results.

Key Features of the 3nh YL4668 Spectrophotometer

1. 256-Element Dual-Array CMOS Image Sensor

Higher optical resolution ensures the instrument’s measuring speed, precision, stability, and inter-instrument agreement consistency. By mastering this core optical technology, it achieves full data compatibility on the same platform with leading international reference standards.

2. Full-Spectrum LED Light Source Implementation

The integrated full-spectrum LED light source ensures a complete and uniform spectral power distribution across the visible light band. This effectively eliminates the spectral deficiencies common to basic LEDs at specific wavelengths, guaranteeing maximum measurement precision alongside exceptionally low long-term maintenance overhead.

3. Concave Diffraction Grating Spectrophotometry Technology

By utilizing high-performance concave diffraction grating technologies, the optical system yields a much finer spectral resolution, translating into significantly more accurate and reliable color calculations.

4. Premium Industrial-Grade Build Quality

Powered by an industrial-grade real-time microprocessor system, the instrument supports high-speed Bluetooth 5.0 wireless data streaming that is remarkably stable, resilient, and secure.

5. Extensive Color Spaces and Standard Illuminants

The system supports a diverse range of international color spaces including CIE LAB, XYZ, Yxy, LCh, CIE LUV, Munsell, s-RGB, HunterLab, βxy, and DIN Lab99, paired with an exhaustive array of standard illuminants: D65, A, C, D50, D55, D75, F1, F2 (CWF), F3, F4, F5, F6, F7 (DLF), F8, F9, F10 (TPL5), F11 (TL84), and F12 (TL83/U30). This massive optical framework satisfies specialized inspection profiles under highly distinct measurement environments.

6. High-Efficiency Production Throughput

A complete data capture and processing loop executes in a rapid 200 milliseconds, enabling automated production systems to audit and screen over 400,000 sample targets per day.
