Cobb Sizing Tester for Paper
纸张可勃吸水度测定仪
How much water a liner or writing paper soaks up decides print quality and box performance. The Cobb tester exposes a 100 cm² area to 100 mL of water, typically at 23 °C, for 60 s as standard or 30–180 s. After blotting under a defined roller load, the gain is weighed to 0.001 g.
