Product Description Product DescriptionTo determine the water absorptiveness of sized paper and board, including corrugated fiberboard, under standard conditions. It may not suitable for paper of grammage less than 50g/m2 or embossed paper. It is not suitable for porous papers such as newsprint or unsized papers such as blotting paper or other papers having a relatively high water absorptivenss for which ISO 8787 is more suitable.This instrument is only capable of testing surface water absorption of paper and board. It is not applicable to exactly evaluate the writing performance of paper and board.StandardISO535 (Paper and board-Determination of water absorption-Cobb method)GB/T1668 (Paper and board-Determination of water absorption-Cobb method)GB/T1540 (Paper and board-Determination of water absorption-Cobb method)TAPPI T441 Water absorptiveness of sized(non-bibulous) paper, paperbaord, and corrugated fiberboard(Cobb test) Test PrincipleA test piece is weighed immediately before and immediately after exposure for a specified time of one surface to water, followed by blotting. The result of the increase in mass is expressed in grams per square meter(g/m2)COBB DefinitionThe value of paper and cardboard surface water absorbing capacity (Cobb): the unit area of paper and cardboard in a certain pressure and temperature, within the time specified the absorption of water by surface to g / m*m meter. The specific formula is as follows: C = (G2 - G1) x 100.C - value of Cobb water absorption; G2 - the sample quality after absorbing water; G1 - the sample quality before absorbing waterProducts PresentationProduct ParametersModelY025Measurement length250±1mmShrinkage measurement accuracy0.1%Shrinkage force measuring range0~25NShrinkage force measurement accuracy0.1NHeating rangeRoom temperature~250oCTemperature Control Precision±0.1oCTiming range0~999SPower supplyAC220V 50HzOverall DimensionLxWxH:520mmx375mmx510mmWeight35kg More ProductsCompany ProfileOur ExhibitionOur CustomersOur AdvantagesFAQQ: How is your service? - All of test devices will be calibrated and debugged before delivery to guaranty the quality. - Our professional after-sale team will help you solving any problem within 24 hours* 7 days by emails or videos - English operation manual and operation video will guide you how to use it. - On-site machine training & installation can be provided with certain charges.Q: What's your warranty period?A.12 months.
