matching options.

Technology advantages
1、Dual light path spectral analysis technology
Can acquire data from measurement sample and environmental reference in machine,
in order to ensure precision and long-term stability of the instrument.

2、Uses D/8 lighting and observation condition, has both SCI and SCE measurement modes
Uses D/8 lighting and observation condition recommended by CIE, satisfies different industries’
color measurement needs; can provide both SCI (Specular component included) and SCE (Specular
component excluded) color measurements, and provide full insight of the color data.

3、Light source is pulse xenon light
Uses pulse xenon light as light source, and covers both UV and visible spectra. Can measure dark
colors precisely and provide color data, and eliminate the effects of stray light. Warm-up is not needed
before the measurement.

4、Adjustable UV light source
Can adjust the percentage of the UV component of the light source

5、Can operate on the instrument with extra large display screen
The user can complete measurement without connection to the PC machine. The user can also view
measurement results and complete settings on the large display screen. Or the user can use the supporting
color management and color matching (ColorMatch) software.

6、Four measurement calibers.
Easy to adjust measurement caliber, with largest caliber being 25.4mm. This can satisfy the
measurement needs of samples of different sizes. CS-820 can measure the color data of opaque samples,
or measure the transmission and opacity of transparent or semi-transparent samples.

7、Unique calibration white board design
Can easily fit the calibration white board on the measurement port to ensure the accuracy of white
calibration, and guarantees high precision measurement.

8、Flexible measurement fixtures
Can fit samples of different sizes and thickness on the measurement port, and eliminate the effects
of stray light on measurement results.
