Air Permeability Tester Vs. Helium Porosimeter: What's The Difference?
Air Permeability Tester and Helium Porosimeter are machines that have hastened industrial processes making them cost-effective and less time-consuming. However, when you're faced with choosing one of these machines for your particular industry, you need to know a few things. First, how do both of these differ, and second, which of these is suited for your industry? So, without further ado, let's discuss the key differences among both of these machines. Helium Porosimeter vs. Air Permeability Tester Helium Porosimeter The Advanced Helium Porosimeter measures the true density and volume of the given samples, including ash coal, char, and many other particles. The test is used to determine the powder bulk of solids, including calcinated petroleum coke. The true volume of a solid is calculated from the pressure drop when an estimated gas containing the sample can expand into the chamber. Hence, the true volume obtained after the porosimetry excludes the pore volume accessible t...
