Product Description


Tabletop spectrophotometer CS-820 has the advantage of excellent inter-instrument agreement, high accuracy and good replicability. It could meet your requirement for both color quality control and color matching easily.


1. Transmission D/0 Structure and Reflection D/8 Structure

2. Double Optical Paths Spectral Analysis Technology

It could get the measurement sample data and internal environment data at the same time to make sure the testing accuracy and stability for long time running.

3. Compatible with SCI/SCE Measurement

Adopt D/8 illuminant geometry recommended by the CIE to meet the color testing requirement for different industries. It could measure with SCI and SCE to see the color data change more clearly.

4. Four Testing Calibers

It is easy to adjust the testing calibers. The largest caliber diameter reaches 25.4mm. It could test the sample with different sizes. CS-820 is not only suitable for testing the color of opacity sample, but also suitable for transparent or translucent sample’s transmittance and turbidity.
5. Large screen display and Stand-alone operation
It could finish the sample test without connecting with the computer. Large screen display to make sure customer could see the testing result directly and clearly and it will be more convenient to set the instrument status. The color quality management software and color match software are optional according to customer’s need.

6. Unique Calibration Board Design

Fix the calibration board on the testing caliber to make sure the accuracy of the white calibration and guarantee the high accuracy for measurement.
7. Flexible Test Fixture
It could fix the sample with different size and thickness on the testing port tightly in case of stray light entering to affect the testing accuracy.


Wide application, suitable for liquid and solid. For any question, please inquire us by offering industry and product.

Suitable for textile and color master batch.
