1.CS-820 Colour Spectrophotometer for Textile Advantages
1).Transmittance and reflectance in one instrument
2).Simultaneous SCI/SCE measurement
3).4 Testing Calibers
CS-820 colour spectrophotometer contains 4 kinds of testing calibers and the largest reaches 25.4mm.
4).Double optical path spectrum analysis technology
5).It is with large display screen. So the testing result could be directly and clearly seen without connecting with PC.
