What your porosity lab actually checks
Full pore range, one technique
From 3.6 nm to 180 µm in a single mercury-intrusion workflow — with fractal, tortuosity and permeability from the same data. The pore structure your process and models rely on, not two partial datasets.

What the BELPORE is
The BELPORE is a series of mercury porosimeters from Microtrac. Mercury does not wet the sample, so it enters a pore only under pressure, and the narrower the pore, the higher the pressure it takes. The instrument raises the pressure step by step and records how much mercury goes into the sample; the Washburn equation turns each pressure into a pore diameter. The series has three instruments. The LP degasses the sample, fills the dilatometer with mercury and measures the large pores at low pressure. The MP and HP take over for high-pressure porosimetry and reach the small pores. They do not run on their own: every sample passes through the LP first, so a BELPORE is configured as LP + MP — for larger sample volumes such as concrete or mortar — or LP + HP, for the full range from over 1 mm down to 3.6 nm. From the intrusion curve the BELPORE reports pore size distribution, pore volume, specific surface area, porosity, density and particle size distribution.

Which dilatometer for which sample
Three dilatometer types cover all measuring tasks. They stand vertically in the instrument for safe handling.
| Type | Capillary · volume · max. solid sample (d × h) · fits |
| Standard | 3 mm · 15 cm³ · 12 × 46 mm · LP, MP, HP 6 mm · 35 cm³ · 25 × 25 mm · LP, MP |
| Professional | 3 mm · 8 cm³ · 11 × 35 mm · LP, MP, HP — screw cap and integrated opening aid |
| Ultra-macropore (UMP) | 6 mm · 50 cm³ · 25 × 25 mm · LP |
All three take powders and solids. PoreInspect corrects for the blank value and checks and corrects for sample compressibility, then offers pore models, fractal dimension, tortuosity and permeability. The raw data stays stored.
Three instruments, one pore range
Pressure build-up is controlled by P.A.S.C.A.L. — Pressurization by Automatic Speed-up and Continuous Adjustment Logic — which follows the real pore system. That shortens measuring time while keeping equilibrium conditions. Filling is fully automatic and vertical under constant high vacuum, and the mercury cleaning set lets you reuse the mercury.
Where the BELPORE stops — and what to take instead
Mercury intrusion measures pores that are open to the surface, from 3.6 nm up. For micropores and the smallest mesopores, and for BET surface area by gas adsorption, look at the BELSORP MINI X or the BELSORP MAX X. For true (skeletal) density by gas displacement there is the BELPYCNO. And the BELPORE works with elemental mercury: your lab has to handle, store and dispose of it under its own EHS rules.
