Designed for Compact, Fast, and Easy Operation
The Grace Instrument M9140 Porosimeter is designed to measure the effective porosity of a core sample with high-precision. Effective porosity is the percentage of all the interconnected pore space to the whole core sample and is critical to considering the suitability of rocks or sediments of oil or gas reservoirs.
The M9140 Core Porosimeter utilizes Boyle's Law to calculate the volume through pressure change during the expansion of helium or nitrogen.

Efficient, Dependable Design
A Microsoft Excel® spreadsheet template is provided with each unit to calculate the porosity using the pressure reading on the digital display. The M9140 measures core samples up to 1.5” in diameter and up to 3” in length. Other sample holder sizes are also available.
