  • Spectrophotometer for Pencil Surface Color Measurement

  • We will introduce how to measure the color of the pencil surface.
    The First Step: Prepare 2 samples and spectrophotometer CS-600B (4mm).


    Our instrument is with camera view that could see the testing area clearly. With the camera view we could make sure the pencil surface is fully cover the testing aperture to make sure no light will enter into the instrument.
