Advanced Permeability Porosimeter

The PMI Advanced Permeability Porosimeter is a versatile and accurate instrument used to determine properties such as particle size, particle distribution, pore tortuosity, pore number fraction, pore throat ratio, pore fractional dimensions, permeability, material compressibility, total pore volume, surface area, and bulk and absolute densities of solid and powder samples. With unlimited user-defined data-points, automated data collection and reduction, non-destructive testing, and the least mercury exposure of any porosimeter on the market, PMI's Permeability Porosimeter is safe, reliable, and precise. It also allows testing under ambient or elevated temperatures to simulate actual operating conditions.
