              • Benchtop Spectrophotometer of CS-820N for metal button Color Measurement

              •                                                                   


                Recently, we receive a custom inquiry for measuring metal button color. We separately measured the following two samples as target sample and sample to compare the LAB value.

                                                     
                                                                                               Sample

                Today we will introduce how to measure it with Benchtop spectrophotometer CS-820N.
                It has 4 kinds of test calibers, we chose 6mm aperture size to measure the metal buttons.


                Test Condition
                1. Mode: Reflectance
                2. Light Source: D65
                3. Parameters need to Measure: CIE L*a*b, ΔE*ab


                Test Method

                1. One sample measure one same point to get the test result

                  The following are the test results for all 2 samples

                Sample Name

                Parameters

                Target sample

                sample
                 

                Color difference


                Test result
                L 65.15 65.03 dL*=-0.11 Pass
                 
                a 1.28 1.10 da*=-0.18 Pass
                b 8.37 8.51 db*=0.14 Pass
                 
                Total result dE*ab
                0.26 Pass



                Benchtop spectrophotometer with large aperture 25.4mm is very suitable to measure metal materials. Instrument repeatability and precision are both very good.
                If any similar project inquiry, you are welcome to contact us for more details. We will help to recommend the most suitable instrument for customers.
