DSCD-950P Benchtop Spectrophotometer is an intelligent, convenient and high precise spectrophotometer. It adopts 7 inches touch screen, full-spectrum capability, and an Android operating system. Illumination modes include reflection D\/8\u00b0 and transmission D\/0\u00b0 (with UV inclusion\/exclusion measurements). It offers accurate and stable color measurements, a large storage capacity, and robust expansion capabilities on the PC end, making it suitable for laboratory color analysis and communication.<\/p>\n

Introduction:<\/strong>
\n- Adopts reflectance D\/8\u00b0 and transmittance D\/0\u00b0 geometry to measure both opaque and transparent materials.<\/strong><\/p>\n

\"\"<\/p>\n

- Dual Optical PathsSpectrum Analysis Technology<\/strong>
\nThis technology can simultaneous access to both measurement and instrument internal environmental reference data to ensure instrument accuracy and long-term stability.<\/strong><\/p>\n

\"\"<\/p>\n

- Compatible with SCI\/SCE measurement, Support SCI+SCE Measurement<\/strong>
\nInstrument adopts D\/8 geometry which is highly recommends by CIE (International Commission on Illumination) to meet color measurement of different industries.It supports both SCI (specula component included) and SCE (specular component excluded) mode for better detect of color change.Fast SCI+SCE measurement, test time only need less than 4s.<\/strong><\/p>\n

\"\"<\/p>\n

- Rotatable Touch Screen with Android Operate System<\/strong>
\nScreen position and direction can be adjusted according to the instrument test methods.<\/strong><\/p>\n
