The answer is permeability testing. These tests help us understand how easy or hard it is for air, water, or gas to move through something.

In this blog, we will explain in very easy words five important types of permeability tests:

• Diffusion Permeability Test
• Gurley Permeability Test
• Liquid Permeameter
• Capillary Flow Porometry Test
• Gas Permeameter

All of these are available at Porosity Permeability Testing, your trusted partner in material testing.

What Is Permeability?

Permeability means how easily a gas or liquid can move through a material.

• If a material has high permeability, it lets gas or liquid pass through easily.
• If it has low permeability, it blocks flow or slows it down.

Permeability testing is very important for many industries, including:

• Packaging
• Filtration
• Construction
• Medical
• Oil and gas
• Textiles

Now let’s look at the different types of tests we do at Porosity Permeability Testing.

1. What is a Diffusion Permeability Test?

A diffusion permeability test checks how gases pass through thin materials like films or membranes.

It tells us:

• How much gas passes through over time
• How fast the gas moves
• If the material is good for blocking air or keeping it in

This test is great for things like food packaging, where you don’t want oxygen to get in, or for medical bags that must hold special gases.

At Porosity Permeability Testing, we use modern equipment to test how gases move through different materials. This helps companies pick the best material for their needs.

2. What is the Gurley Permeability Test?

The Gurley permeability test is a very common method to test how fast air can pass through paper, fabric, or film.

How does it work?

• We let air pass through a material under a set pressure
• Then we measure the time it takes for a certain amount of air to go through
• This time is called the Gurley number

A higher Gurley number means it takes longer for air to pass through — so the material is less permeable.

This test is very useful for:

• Filters
• Packaging materials
• Battery separators
• Medical paper

Our team at Porosity Permeability Testing provides accurate and fast Gurley testing for all kinds of materials.

3. What is a Liquid Permeameter?

A liquid permeameter is a tool we use to test how easily liquid flows through materials like soil, rock, or membranes.

It’s often used in:

• Oil and gas exploration
• Environmental testing
• Construction
• Research labs

This test helps answer questions like:

• Can water flow through this soil or rock?
• How much water can pass through in a day?
• Is this filter material good for liquids?

At Porosity Permeability Testing, we use liquid permeameters to give you real answers about your material’s flow ability. Our results help you make safe and smart choices.

4. What is a Capillary Flow Porometry Test?

A capillary flow porometry test looks at the tiny pores in a material. It tells us:

• The size of the biggest and smallest pores
• How evenly the pores are spread
• How air or gas flows through these pores

This is very helpful for:

• Filters
• Medical devices
• Membranes
• Textiles
• Battery materials

In this test, we let air or gas flow through a wet material. Then we dry it and repeat the test. The difference tells us how big the pores are.

Porosity Permeability Testing offers this advanced test to help you understand pore structure in the simplest way possible.

5. What is a Gas Permeameter?

A gas permeameter is used to test how fast and easily gas flows through rocks, membranes, filters, or films.

It is mostly used in:

• Oil and gas research (to check rock permeability)
• Lab testing for gas barriers
• Filter design
• Geology studies

The gas permeameter test tells you:

• How much gas flows per second
• How tight or open the material is
• Whether the material is useful for holding or passing gases

At Porosity Permeability Testing, our gas permeameters help clients in energy, research, and industrial projects get the data they need.
