Air Permeability Tester and Capillary pressure and resistance Tester are the two machines that have modernized the way industrial testing procedures are conducted. Both machines offer unique features suited to perform complex tasks within minutes, making them both time-saving and cost-effective investments.

Yet, both the Air Permeability Tester and the Capillary Pressure and Resistance Tester are different in functionality, so discussing these in-depth is important. By knowing how the machines perform, you can better understand which one is better suited for your industrial requirements.

So, without further ado, let's start comparing the two.

Capillary Pressure Tester And Resistance Tester Vs. Air Permeability Tester.

• Capillary Pressure And Resistance Tester

The advanced capillary pressure and resistive tester test rock samples held within its chamber using compressive stress. While the tested sample is under compressive stress, the desired properties are calculated. The advanced capillary pressure and resistive tester determine the samples' properties that are cut at certain confining pressure ranges while measuring their resistance.

Noteworthy specifications include Permeability Ranges of up to 5 Darcy and the Confining Pressure ranges up to 10,000 psi or higher. The Liquid Flow Range starts at 0.01-10cc per minute and can be wider should you want to test with more liquid.

What's more, the Flow (Pore) Pressure Range is up to 750 psi, and the Capillary Pressure reaches up to 1500 psi. However, there's room for reaching higher pressures, and the Standard Core Plug Diameter is only 1.5 inches.

The core's plug length can be 5cm long or 7 cm long, depending on your requirements. A single-phase power phase requires 220-240 VAC 50 Hz consumption, and the machine's weight is 110 kg.

• Air Permeability Tester

This machine determines the resistances of fabrics that include knitted, non-woven, woven textile material to airflow passage. Consistent air pressure is applied to the sample while it is firmly clamped in the selected test area's test rig. The sample is then loaded to the test area of the machine easily through the means of a pneumatic holder.

The test starts when the holder is pressed down. The air permeability tester with the vacuum pump draws air through an interchangeable testing head with a circular opening. The test pressure that was pre-selected is automatically maintained.

Later, after a few seconds of air permeability, the sample results are digitally displayed in the pre-selected measurement units on the included LCD screen. Lastly, the test holders are released, and the vacuum pump is shut off.

The air permeability tester considers a testing area of 5,20,50, and 100 cm^2. The pressure range is 1~4000 pa with a maximum sample thickness of 8mm. This thickens the air permeating rate at a differential pressure of 1~40000 mm per second.

As for the power consumption requirements, the device only requires 220/110 V with 50/60hz and 2 KW. The various power options make this machine suitable for a variety of industrial tasks. The air permeability tester weighs 80 kg, and its dimensions are 1250 x 700 x 1250 mm (L x W x H).

The Differences In These Machines

As mentioned before, both these machines have unique functionalities that are suited for different industrial processes. Firstly, the air permeability tests are more affordable and maintain the confidence of the results. The machine gives quick and straightforward results in the measurement unit of your choice. Furthermore, it's also intuitive as the automatic ranging system detects the installed test head's size and determines its appropriate pressure range.

On the other hand,

The Capillary Pressure and Resistance Tester performs comprehensive rock sample tests to find out their resistances.

Conclusion,

Both of these devices are best suited for researching, developing, and assuring the quality of processes. However, the one that fits your industrial requirements should be your ultimate choice.
