NS820 ultra high precision NS series spectrophotometer Introduction
The NS820 ultra-high-precision spectrophotometer uses the spectrophotometric colorimetric instrument to measure the spectral characteristics of the reflected light and then calculate the Lab value according to the equation of the CIE standard observer function. In addition to displaying data in various color spaces, the colorimeter using spectrophotometric analysis can directly display spectral data and provide more detailed information about the color of the object.
