3nh Non-Contact Spectrocolorimeter for Benchtop and Inline Color Measurement
3nh Non-Contact Spectrocolorimeters | Special Samples and Production Lines
How to Choose a Non-Contact Spectrocolorimeter: Sample Type, Distance and Line Requirements
3nh non-contact spectrocolorimeters measure color without placing the instrument against a sample. They may be considered for liquids, powders, pastes, wet films, easily scratched surfaces and other materials that should not be touched during measurement. Depending on the sample and configuration, non-contact measurement can also support conveyor, robot-assisted and automated inspection workflows.
Before selecting a system, confirm whether the sample moves, its surface reflectance, a stable working distance, the target area, ambient light, external triggering, data output and line integration. Then compare the YL70, YL72, YL3120, YL3160, YL4520, YL4560 and YL4568 against the real process.
Quick comparison of non-contact models
YL70
45/0 inline non-contact color measurement
For automated lines, robot integration, online color monitoring and special samples. Confirm fixed distance, installation space, sample movement and communication requirements before integration.
YL72
45/0 measurement for special samples
For liquids, pastes, powders and surfaces that may be damaged by contact. Confirm working distance, positioning and sample condition; automation suitability depends on the installation.
Compare these models for conveyor or robot-assisted processes, automated monitoring and color-data transfer. Review measurement speed, mounting, sample state and communication needs.
For applications requiring fixed 45°/0° geometry with liquids, powders, pastes or special surfaces. Compare the actual sample and measurement requirements before choosing.
YL4568
Inline 45°/0° non-contact color measurement
For integrating 45°/0° non-contact color measurement into an automated line. Confirm sample type, fixed distance, line speed, mounting location and communication method.
What to confirm before implementation
Sample type
Identify solids, liquids, powders, pastes, wet films or other special surfaces.
Working distance
Check whether distance can remain fixed and whether a fixture is needed to position the target.
Sample movement
For conveyors, confirm line speed, measurement position and timing.
Line integration
Clarify external triggers, data output, robot integration and connections to other equipment.
API, database, dynamic decisions, real-time control or production-data connections require engineering review based on the equipment and site conditions.
When might a contact spectrocolorimeter be a better fit?
Non-contact measurement is not ideal for every sample. If a flat sample can be contacted consistently and the task is incoming inspection, lab color-difference control, standard-color setup or routine QC, also compare a contact spectrocolorimeter.
