This instrument measures the whiteness of various powders, such as starch, wheat, sugar, drugs and cement. It is smaller and lighter than the conventional C-100. The amount of sample required for measurement has been reduced by redesigning the sample case. In addition, sample packing has been made easier. Less time needed for preparation and a shorter warm-up period sensitivity adjustment time at start-up results in faster measurements. The use of LEDs for the light source means lower power consumption and internal heat. Regular cleaning of the glass filter is necessary for accurate measurements. A redesigned filter section simplifies cleaning.
