Poroscope Plus measures the time it takes for air to flow into a known volume of a sealed, evacuated chamber in the concrete. While the vacuum reduces from -55 Kpa to -50 Kpa, a measure of air permeability is determined.
For water permeability, Poroscope Plus uses the same chamber filled with water, and measures the total time in seconds for a volume of 0.01 ml of water to escape. Surface porosity is determined in like manner using a specially designed surface chamber.
Both air and water permeability are measured by the same instrument
Permeability both at the concrete surface as well as within the concrete mass can be determined
Porosity in sealants and surface mortars can be checked
The test is non-destructive (only a small plugged hole required) and can be completely carried out on site
Each test can be completed in only a few minutes and gives reliable reproducible results
The test enables meaningful concrete durability predictions to be made
