纸张不透明度测定仪
Lightweight printing paper, book paper and newsprint are judged on show-through, which this tester expresses as opacity from the contrast between black and white backings. Diffuse illumination and 0° viewing over about 30 mm give ±0.2 opacity unit repeatability, with opacities up to 100%.
