A water absorption testing device according to ISO 8361 is used to determine the water absorption capacity of porous materials under defined conditions. It enables controlled exposure of the sample to water over a specified period and under standardized environmental parameters. The increase in mass of the sample is measured to assess its porosity and absorption behavior. The device is characterized by precise control, reproducible test results, and ease of use, making it suitable for material testing, quality control, and research applications.
