PoreMaster® series

The safest and most easy-to-use automated mercury intrusion porosimeter

The PoreMaster® series of mercury intrusion porosimeters significantly minimizes exposure to both liquid mercury and mercury vapor, ensuring maximum safety for operators. Many automated and ergonomically considered features provide users with a simple operation experience for determining the size distribution and volume of pores within macroporous materials. Four distinct models are available to fit the specific pore size and sample throughput requirements of customers in a wide range of industries using this technology, such as oil and gas exploration, pharmaceuticals, ceramics, and building materials.
