Using Automated Humid Air Porometer for R&D: What`s The Benefit?

Automated Humid Air Porometer is widely used in industries, research labs, and for development purposes. This machine has proved its presence among the masses and is embraced by researchers across the globe. This blog intends to highlight the benefits of this machine and how it leverages in the R&D sector.

Working Principle of Automated humid Air Porometer

This machine is said to deduce accurate results due to various reasons, especially the principle it works upon.

A wetting liquid is allowed to fill the sample's pores, and a non-reacting gas is used to displace the liquid from the pores. Later, the gas pressure and its flow are accurately measured. The gas pressure which is required to remove the liquid is calculated with the following formula;

D = 4 γ cos θ / p

D denotes the pore diameter, θ is the liquid contact angle, γ denotes the liquid’s surface tension, and p denotes differential gas pressure.

From gas pressure and flow pore diameter, size distribution and gas permeability are calculated.

Benefits & Capabilities of Automated Humid Air Porometer

This machine is a perfect match for research and development purposes. Here are some of the benefits and capabilities.

• It can measure liquid flow rate through sample when the pressure is applied on excess liquid

• It can measure breakthrough pressure

• Can perform an integrity test

• Has multiple sample chambers

• Has the capability to perform smoothness test and burst pressure test

• Can withstand temperatures up to 200°C

Features of Automated Humid Air Porometer

This machine not only reduces test duration but also yields reproducible results. It is super effective and a great addition to research and development projects.

At the bottom of the piston rod, the sample chamber has O-rings on the outside that prevent leaks and sample housing and sample chamber.

The machine tests exactly the same area, and there is no need to undo the chamber for wetting; also, the need for cutting samples is eliminated, which ensures that the sample doesn’t get disturbed in the entire process.

Automated Humid Air Porometer can test small samples and complete parts. It has the capability to adjust as per different sample geometries, for instance, rods, tube fibers, hollow, powders, and cartridges. It can test a variety of wetting liquids, for instance, water, silwick, alcohol, and galwick.

To conclude..

Researchers can now see the entire process through see-through chambers for the visual observance. The machine is fully automated and computer-controlled, which minimizes margins for errors. The numerous capabilities and features are an added bonus.
