The YL4668 spectrophotometer is a color measuring instrument that adopts D/8 (diffuse illumination, 8°direction reception, SCI includes specular reflection light) standard color measurement instrument, non-contact test between test probe and tested sample, to achieve liquid and sauce , powder and other non-contact precision color measurement. The simple probe design allows this product to be placed anywhere on the automated production line for precise color measurement and color quality control. It is widely used in cosmetics, fruits and vegetables, food hygiene, plastic electronics, paint and ink, printing, ceramics and other industries. It can be used for fluorescent sample measurement. Its unique innovative design can not only provide non-contact measurement solutions directly from the production line, but also ensure stable and high-precision measurement results.

數量

1. 256-pixel dual-array CMOS image sensor

Higher optical resolution ensures the measurement speed, accuracy, stability and consistency of the instrument, mastering the core technology, and achieving complete compatibility on the same platform with international standards.

2. Using full-spectrum LED light source

The full-spectrum LED light source ensures sufficient spectrum distribution in the visible light range, avoids the lack of LED spectra in specific bands, and ensures the accuracy of the instrument's measurement results and low-cost maintenance.

3. Concave grating spectroscopy technology

Using concave grating spectroscopy technology, it has higher resolution and makes color measurement more accurate.

4. Higher quality

Using industrial-grade real-time processing MCU, supporting Bluetooth 5.0 transmission is more stable and reliable.

5. Multi-color measurement space and observation light source

Provide CIE LAB, XYZ, Yxy, LCh, CIE LUV, Musell, s-RGB, HunterLab, βxy, DIN Lab99 color space, and D65, A, C, D50, D55, D75, F1, F2 (CWF), F3, F4, F5, F6, F7 (DLF), F8, F9, F10 (TPL5), F11 (TL84), F12 (TL83/U30) multiple observation light sources can meet the special measurement requirements under different measurement conditions.

6. Efficient

A complete measurement cycle only needs 200 milliseconds, and more than 400,000 samples can be measured per day.
