1. Advantages of CS-820 Transmission and Reflectance Bench-top Spectrophotometer

1).Transmission and reflectance in one instrument

Transmittance measurement: D/0 Geometry (diffused illumination, 0 degree viewing) to measure liquid APHA, Pt-Co index, Gardner index and other parameter measurement.

Reflectance measurement:D/8 Geometry (diffused illumination, 8 degree viewing) to measure reflectanceHTB1jqmROpXXXXcFaXXXq6xXFXXXp - CS-820 Transmission and Reflectance Bench-top SpectrophotometerHTB1IznlOpXXXXcaXXXXq6xXFXXXP - CS-820 Transmission and Reflectance Bench-top Spectrophotometer

2).Simultaneous SCI/SCE measurement

3). 4 Testing Calibers

CS-820 contains 4 kinds of testing calibers and the largest reaches 25.4mm to meet the color measurement requirement for different kinds of materials.

4).Double optical path spectrum analysis technology

Simultaneously obtains the sample reflection signal and the light source intensity signal, guarantees the instrument measuring accuracy and the long-term repeatability.

5).It is with large display screen. So the testing result could be directly and clearly seen without connecting with PC.HTB1PBKQOpXXXXbnapXXq6xXFXXX0 - CS-820 Transmission and Reflectance Bench-top Spectrophotometer

 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 very easily.
