Online Benchtop Spectrophotometer YL4668L with d/8
The online Benchtop spectrophotometer YL4668L is a color measuring instrument that adopts the D/8 (diffuse illumination, 8° viewing, SCI Specular Component Included) standard, implementing non-contact precise color measurement of objects, like liquids, powders, pastes etc. The succinct design of probe allows this instrument to be placed anywhere on the automated production line for accurate color measurement and color quality control. It is widely used in cosmetics, fruits and vegetables, food hygiene, plastic electronics, paint and coatings, ink, printing, ceramics and other industries. It can also be used for fluorescent sample color measurement. Its unique innovative design can not only provide non-contact measurement solutions directly for production line, but also ensure stable and high-precision measurement results.
Features of non-contact spectrophotometer
1. Non-contact measurement
Accurate color data measurement can be achieved with a distance of 3mm from the measured plane
2. 256-pixel dual-array CMOS image sensor
Higher optical resolution ensures the measurement speed, accuracy, stability and consistency of the instrument. Master the core technology, developed on the same platform as the international standard, achieve fully compatibility.
3、Adopt Full-spectrum LED Light Source
The full-spectrum LED light source ensures sufficient spectral distribution in the visible light range, avoids the lack of LED spectrum in specific bands, and ensures the accuracy of instrument measurement results and low-cost maintenance.
4、Concave grating spectroscopic technology
Using concave grating spectroscopic technology, it has higher resolution and makes color measurement more accurate.
5、Higher Quality
Adopt the MCU with industrial-grade real-time processing. Supports Bluetooth 5.0 transmission, which is more stable and reliable.
6、Multiple Color Measurement Spaces and Observation Light Sources
Provide CIE LAB, XYZ, Yxy, LCh, CIE LUV, Musell, s-RGB, HunterLab, βxy, DIN Lab99 color spaces, 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 special measurement requirements under different measurement conditions.
7、High Efficient
A complete measurement cycle takes only 200 milliseconds, and more than 400,000 samples can be measured per day.
