Porosity Measurement Instrument

The porosity tester measures the ratio of internal void volume to total volume of a material using the gas displacement method. The instrument injects inert gas into the sample chamber and calculates the pore volume based on pressure changes. It is used to evaluate the structural characteristics of porous media such as filter materials, catalyst supports, and battery separators.
Selection
When selecting, consider matching the material's pore size range with the instrument's measurement range, ensuring the gas type is suitable for the sample properties, and verifying that the temperature control system meets the testing conditions. The sample size must be compatible with the fixture specifications, the operation interface should align with user habits, and the data output format must integrate with the existing system. Additionally, maintenance cycles and consumable costs should be factored into long-term usage evaluations.
