8. Advantage of Bench-top Spectrophotometer CS-821N.

1). Simultaneous SCI/SCE measurement.
2). 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 reflectance.
3). 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.
4). Testing Calibers
CS-821N textile spectrophotometer contains 4 kinds of testing calibers and the largest reaches 25.4mm to meet the color measurement requirement for different kinds of materials.
5). It is with large display screen. So the testing result could be directly and clearly seen without connecting with PC.
