Advanced, Cost-Effective Device Designed for Easy Installation and Fast Operation
The Grace Instrument M9175 Steady State Permeameter is a robust solution for measuring gas permeability of a high permeability core sample under confining pressures up to 1,500 psi. Using the steady state method, the M9175 calculates permeability by measuring the differential pressure and flow rate of testing media as it flows through a core sample. Innovative design allows for easy setup, use, and cleaning. Standard unit is compatible with nitrogen testing media (helium optional)*.

Versatile Device Supports High Permeability and Klinkenberg-Corrected Permeability
The M9175 measures gas permeability of high permeability cores using the steady state flow method. The gas at the entrance valve is initially pressurized. All valves are then opened, allowing the gas to flow through the core. At steady-state flow conditions (dP/dt=0 and dq/dt=0), the gas pressure and flow rate are measured and used to calculate the permeability using the integrated form of Darcy’s Law for compressible fluids.

Permeability has been demonstrated to be a function of reciprocal pressure. The M9175 is also able to calculate the Klinkenberg-corrected permeability using gas permeability measurements at different pressures.

Preconfigured PC Includes Complementary, Advanced Grace Instrument M9175 Software
Advanced, easy-to-use software is included free with each unit. No software installation or setup is required!

M9175 software is intuitive and compatible with all versions of Windows. A preconfigured computer, including all necessary hardware and software components, will be set up by Grace Instrument. The software comes preinstalled on the PC by a Grace Instrument technician for your convenience.

This intuitive, user-friendly software automates testing and accurately records results from the unit to the PC, simplifying the testing workflow. Valves are automatically opened and closed, and almost all other testing procedures are fully automated step-by-step from start to finish. The user only needs to make very minimal regulator adjustments during testing, maximizing workflow efficiency. M9175 software automatically measures, collects, and calculates data for the user. It can also calculate Klinkenberg-corrected permeability using gas permeability measurements at different pressures.

Data is saved in .csv file format and can be conveniently exported to Excel or any other spreadsheet software for further manipulation and analysis.

The software also generates charts and reports. In particular, Klikenberg and low permeability data have special chart views for easy comparison.

Tabletop Device Easy to Clean and Maintain
This device fits easily on a standard tabletop or lab workbench. The chassis of this device is easy to wipe down. Cleanup between tests is quick and easy.
