CS-820 All-in-one Spectrophotometer

Bench top spectrophotometer CS-820 can measurement both reflectance and transmittance.It is with the best repeat-ability Delta E*ab 0.015.Four apertures to meet all color measurement requirement.

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

Brief Introduction

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.

4. Four Testing Apertures

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.

5. Large Screen Display

It could finish the sample measurement without connecting with PC. Large screen display to make sure customer could see the testing result directly and clearly. It will be more convenient to set the instrument status. The color match software are optional according to customer’s need.

6. 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.
