The IGT SizeOscope is an automated device to determine the sizing of paper and board through the change in reflectivity. It is especially designed to be used with watery liquids of all kinds, its materials coming in contact with the liquid are suitable for all usual liquids common in the paper industry.
The IGT SizeOscope is an excellent tool to measure the absorbtion resistance of your substrate and barrier coatings.
The whiteness decreases because of the show-through of the penetrating ink. The measurement starts when a high contrast liquid contacts the paper, the measured reflection starts at 100 % and the penetration is visible as a reduction of the reflection. Factors influencing the reflection are brightness,
