YL4560 45°/0° Non-contact Spectrocolorimeter
YL4560 Non-Contact Spectrocolorimeter | 45/0 Measurement with Adjustable Height
The YL4560 uses 45/0 optical geometry and measures without the probe touching the sample. It is intended for color analysis of liquids, pastes, powders, adhesive or contaminating samples, and other materials that are not suitable for direct-contact measurement.
Measurement height can be adjusted to suit sample height and container conditions, including different container sizes, liquid levels, or sample positions. Applications may include laboratory R&D, color data development, batch comparison, quality inspection, and color management on automated production lines.
45/0 non-contact measurement | Adjustable measuring height | Liquids, pastes and powders | Different container heights | R&D and quality control
Non-contact color measurement
The measuring probe does not need to touch the sample. This can help reduce the risk of probe contamination or residue from liquids, pastes, powders, and materials that tend to adhere, and can limit interference with the sample surface.
Adjustable measuring height
The measuring head position can be adjusted according to the sample container, liquid level, and sample height. This provides flexibility when measuring samples in containers of different sizes or heights.
R&D and quality-control workflows
The YL4560 may be used for formulation development, reference-sample creation, batch color-difference comparison, and quality-control records to support consistent color data management.
Common samples and industries
- Liquids, pastes and powders
- Cosmetics, food and agricultural products
- Paints, coatings and inks
- Printing, ceramics, plastics and electronics
YL4560 or YL4520: how to choose?
For 45/0 non-contact color measurement at a fixed height for general liquids, powders, or pastes, compare the YL4520 non-contact spectrocolorimeter. If container height, liquid level, or the actual measuring position varies and greater height adjustment is needed, evaluate the YL4560. Final selection should be based on the sample and measurement setup.
What to confirm before installation
Confirm sample type, container dimensions, sample or liquid-level height, surface uniformity, stable measuring distance, measuring aperture, measurement position, ambient-light control, calibration procedure, and internal acceptance criteria. For automated installations, also review line speed, mounting space, and sample positioning.
YL4560 Frequently Asked Questions
What samples can the YL4560 measure?
It can be evaluated for liquids, pastes, powders, and other materials that are inconvenient to measure by direct contact. It is especially relevant when sample or container height affects the measuring position.
What is the main feature of the YL4560?
In addition to 45/0 non-contact measurement, the measuring height can be adjusted to suit the sample and container, including different liquid levels and sample positions.
How does it differ from the YL4520?
The YL4520 can be considered for fixed-height 45/0 non-contact measurements. The YL4560 focuses on adjustable measuring height for applications with varying container heights, liquid levels, or sample positions. Compare both models against the actual workflow.
What should I consider when measuring liquids?
Keep the liquid level, container shape, bubbles, sample flow, and measurement position consistent. Maintain a stable distance and sample condition between measurements.
Can it be used for powder samples?
Powder applications can be evaluated. Pay attention to fill height, surface leveling, particle distribution, and sampling technique so that sample preparation does not create excessive variation between measurements.
Is it suitable for laboratory R&D?
It may support formulation work, reference-sample creation, batch comparison, and color data management, particularly where sample height or container conditions vary.
Can it be integrated into an automated production line?
Automated color measurement may be possible depending on the equipment configuration. Confirm sample positioning, measuring height, distance control, line speed, and available installation space before integration.
What information is useful for a selection review?
Provide the sample type, container dimensions and height, sample or liquid-level position, surface condition, measurement method, automation requirements, current quality criteria, and acceptable color difference.

Selection guidance
The YL4560 is a non-contact benchtop spectrocolorimeter for liquids, pastes, powders, and samples that are unsuitable for contact measurement. Its adjustable measuring height may be useful when sample or container height varies. Before implementation, confirm the container, sample height, distance stability, measuring aperture, camera positioning, calibration procedure, and acceptance criteria. For automated lines, databases, or real-time decision workflows, have an engineer assess the equipment and data format for the actual site.
