Presto's Corrugated Fiberboard Cobb Testing is the best test procedure which is performed to determine the quantity of water absorbency by a paper, fiberboard in a particular time period. The cobb value or water absorptiveness of a substance is defined as the weight of water which is absorbed by the 1 square meter fiberboard in a given period of time. The instrument is designed as per the standard test methods that are introduced by reputed standardization authorities. It is ergonomically designed with the best quality of material so that quality of the specimens can be ascertained in highly precise and accurate manner.
Presto's Corrugated Fiberboard Cobb Testing instrument is the best device that helps to measure the amount of water absorbency in the fiberboard sheets. The device is equipped with the cylindrical container which is fixed with a flat flexible base on which the sample is placed to perform the test. The test specimen is first weighed and then placed it on the flat base of the dry cylinder. Now pour 100cc of water inside the sample and leave it for a given period of time. Now take out the specimen and drain the water with the help of roller and again weight the sample to measure the Cobb Value of the specimen. The instrument is designed keeping in mind the standard test methods. The machine provides highly accurate and reliable test results.

The Tensile testing Machine is highly recommended for evaluating the tensile strength of products and materials. The equipment is based on the Constant Rate of Traverse (CRT) principle. It is equipped with an upper jaw and a lower jaw. Universal Tensile Testing Machine is a reliable piece of equipment which is widely used for checking tensile strength of a product/sample. One of the most common mechanical testing techniques used to determine tensile strength, this is a method wherein controlled tension is applied to a sample until it fully fails.
Thus, the material properties of the sample can be easily determined by this test. It involves measuring the force required to elongate a sample under test to breaking point. Using this test, manufacturers and quality managers are able to determine the core strength of their products.
