About Cobb Sizing Tester
Cobb Tester determines water absorption/penetration (Cobb Value) of paper, paper board, corrugated fiber board and other sheet materials. Cobb value is the Quantity of water in mgs absorbed by surface of 100 cm2 of the specimen on one side only in a specified time under a specified head of water. It measures the weight increase of a sample exposed to water for a given time. The container mounted on a stand and filled with the specified amount of water that can be turned upside down to contact with water with a knob. After the test time has elapsed it is turned back and sample taken for analysis. The filled water can be used several times before it replenished. The lid is clamping by way of spring-loaded finger grips. The Test consists of a Test Apparatus, Roller & Blotting Paper.
