China National Pulp and Paper Research Institute Co., Ltd. (CNPPRI) was founded in 1956, formerly known as the Paper Industry Science Research Institute of the Ministry of Light Industry. In 1999, it was transformed into a technology-based enterprise and is now a wholly-owned subsidiary of China Light Industry Group Co., Ltd., a subsidiary of Poly Group.

China Paper Institute is a professional research institution with abundant scientific and technological resources. It has established the National Engineering Laboratory for Pulp and Paper Industry, the National Standardization Technical Committee for Paper Industry, the National Paper Quality Supervision and Inspection Center, the China Paper Magazine, the Paper Industry Productivity Promotion Center, and the National Paper Industry Information Center. Its main business includes research and development of industry technology, consulting services, engineering testing, and achievement transformation.

China National Paper Institute is a national research and development center for industrialization technology in the paper industry. The scientific research talent team has a reasonable structure, rich research and development experience, complete scientific research methods and equipment, outstanding engineering experimental facilities, and outstanding industrialization ability of technological achievements. Over the years, it has achieved excellent results in pulp and paper technology, and the research and development projects involve various fields of the paper industry. Over the past 50 years, China Paper Institute has completed more than 1700 research projects, of which over 180 have received various awards from the national and ministerial levels. It is a backbone force in promoting technological progress in China's paper industry. China Paper Institute is still a promoter of China's paper industry's foreign technical exchanges and cooperation, actively participating in various professional conferences in the paper industry, undertaking cooperation and foreign aid projects, and cultivating a group of senior engineering and technical talents for the country.

In 2012, China Paper Institute moved to a new location in Zhongguancun Science Park, Wangjing, Chaoyang District, Beijing, and comprehensively updated and upgraded its research facilities, establishing a research and development platform.

Non woven electronic moisture penetration tester

Compliant with standards:
WSP 70.3-EDANA ERT 150.5(02)
WSP 70.7-EDANA ERT 153.0(02)
ISO REFERENCE 9073-8：1995
ISO REFERENCE 9073-13：2001

Product Introduction
1. Liquid penetrability is an important characteristic of non-woven fabrics.
LISTER AC is a recommended product by EDANA.
3. Use electronic methods to test the time it takes for liquids to penetrate the surface of non-woven fabrics.
4. The penetration time of a liquid is the time it takes for a known volume of liquid (artificial urine) to pass through the surface of a non-woven fabric.

Detection method:
1. A certain volume of test liquid is discharged onto the surface of the sample at a standard rate.
2. The instrument will automatically record the time it takes for the liquid to penetrate the non-woven fabric.

Product Specifications
1. Resolution: 0.01 seconds
2. Accuracy: superior to EDANN/INDA standards
3. Re wetting: According to EDANN/INDA standards WSP 80.10 (equivalent to ERT 151.3) and WSP 70.8 (equivalent to ERT 154.0), after completing the liquid penetration time test, the re wetting of non-woven fabrics can be directly tested using the same sample.

Optional professional computing program: for online use with a computer and "WETBACK"
