Product YL3160 Non-Contact Spectrophotometer Features
Non - contact measurement: There is no need to directly contact the sample. This not only avoids damage to the sample but also prevents the instrument from being contaminated by the sample. It is especially suitable for samples that are corrosive, liquid, dusty, etc., which are likely to damage the instrument, as well as soft, easily deformable or uneven-surfaced samples.
Applicable to various samples: It can precisely measure the color of samples in different forms such as liquids, pastes, and powders, meeting the needs of multiple industries including cosmetics, fruits and vegetables, food hygiene, plastic electronics, paint and ink, printing, ceramics, etc.
Avoid cross - contamination: When measuring multiple samples, cross - contamination between samples will not occur due to contact, ensuring the accuracy and reliability of measurement results. This is particularly suitable for industries with high hygiene requirements, such as food, medicine, and cosmetics.

Convenient data transmission: Equipped with various digital interfaces such as USB, RS485, RS232, and Ethernet, it can be easily connected to external devices such as computers, printers, and PLCs to achieve rapid data transmission and sharing. This facilitates data processing, analysis, and storage, and also makes it easy to integrate into automated production systems.
External trigger function: It supports external triggering and can work synchronously with other devices. For example, it can cooperate with sensors or controllers on the production line to achieve automatic measurement and data collection, improving the degree of measurement automation and accuracy.
Analog signal output: It can output analog signals and be connected to other analog devices or control systems to achieve real - time monitoring and adjustment of color parameters, which is applicable to some technological processes that require precise color control.

Flexible measurement: There is no limit to the sample thickness. Only using the test probe makes it more flexible and convenient when measuring samples of different sizes and shapes. There is no need to worry about the impact of sample size and thickness on the measurement results, and it can adapt to various complex sample measurement requirements.
High protection level: With an IP66 protection level, it is waterproof and dust - proof, and can withstand complex industrial environments.

High - precision measurement: Adopting advanced optical technologies such as concave grating spectroscopy technology, 256 - pixel dual - array CMOS image sensors, and full - spectrum LED light sources ensures high optical resolution and accurate spectral acquisition, thus achieving stable and high - precision measurement, accurately measuring the reflectance of objects and various chromaticity indicators.
Fast measurement: The measurement speed is fast. A complete measurement cycle only takes 50 milliseconds at the fastest (100 milliseconds normally), and it can measure more than 1 million samples per day, meeting the requirements of rapid detection in automated production lines and improving production efficiency.

The YL3160 Non-Contact Spectrophotometer, with its technical advantages of high precision, non-destructive measurement, and industrial compatibility, is widely applied across multiple industries including coatings & industrial materials, textile printing & dyeing, automotive interior manufacturing, cosmetics, food industry, cultural relic preservation & special materials, as well as electronics & plastic products. It demonstrates outstanding performance in protecting sample integrity while achieving automated detection scenarios.
