Core Hole Permeability Tester

This instrument can be used to measure the permeability value of core samples. The instrument is designed based on Darcy's law. Under a certain pressure, nitrogen gas flows through the core sample. Due to different permeability of the core, the flow rate and pressure through the core vary. Pressure sensors, flow meters, A/D processors, and microcomputer systems collect these pressure and flow values. After processing by the calculation program, the permeability value is automatically printed.
