Types of Gas Transmittance Meter
 

Differential pressure method tester

The differential pressure method is one of the most widely used techniques for measuring gas permeability. This type of gas permeability tester operates by creating a pressure difference across the material being tested.

 

Manometric method tester

The manometric method gas permeability tester is another popular option. It works by measuring the pressure change in a closed chamber as the gas permeates through the material.

 

Coulometric method tester

The coulometric method gas permeability tester is specifically designed for measuring the permeability of oxygen and water vapor through packaging materials.

 

Infrared method tester

The infrared method gas permeability tester utilizes infrared sensors to measure the gas concentration on both sides of the material.

 

Gas chromatography method tester

The gas chromatography method gas permeability tester is a highly precise and sensitive option. It measures the permeability of various gases by separating and quantifying them using gas chromatography.

 

Dynamic accumulation method tester

The dynamic accumulation method gas permeability tester is specifically designed for measuring the permeability of gases through large samples or packages.

Features of Gas Transmittance Meter

Auto-stabilization detection: Machine learning algorithms monitor gas permeation trends, triggering test cessation once curves achieve steady-state equilibrium for rapid, reliable outcomes.
Triple-module design: Three isolated chambers operate concurrently, facilitating comparative studies or batch sample evaluations to accelerate r&d timelines.
Differential pressure protocol: Precision-calibrated sensors and thermoelectric regulation execute pressure variance analysis with lab-certified stability (<0.5% deviation).
Adjustable testing volumes: Modular chambers adapt to tailored dimensions (customizable volume/pressure ranges), ensuring compatibility with films, foils, or 3D substrates.
Open-source programmable interface: In-house developed software enables scriptable test protocols and cross-platform adaptation to regional regulatory benchmarks.

 

Applications of Gas Transmittance Meter

 

 

Gas permeability test system suitable for food, pharmaceuticals, medical devices, daily chemicals, agriculture, electronics, and sustainable packaging industries, the gas barrier testing machine evaluates the gas transmission performance of films, sheets, paper, packaging materials, and related barrier substrates. Designed to accommodate high, medium, and low gas barrier materials, it provides versatile, high-efficiency detection for oxygen (O₂), carbon dioxide (CO₂), nitrogen (N₂).

 

 

Manufacturing Process of Gas Transmittance Meter

Design: The first step in manufacturing a gas permeability tester is the design phase. Engineers and experts work together to create a design that meets the industry standards and requirements.
Selection of components: Once the design is finalized, the next step is to select the components required for the tester. This includes sensors, valves, pumps, and other necessary parts.
Assembly: The selected components are then assembled according to the design specifications. Skilled technicians carefully put together the different parts to create the gas permeability tester.
Calibration: After the assembly, the tester goes through a calibration process. This ensures that the instrument provides accurate and precise measurements.
Quality control: Before the gas permeability tester is ready for use, it undergoes rigorous quality control checks. This includes testing its performance, durability, and functionality.

FAQ

 

Q: How is gas permeability measured?

A: For obtaining the permeation pure gases one measurers either the rate of permeability pressure rise (usually from a vacuum) in a constant volume/temperature receiver or the volume of permeate gas at a fixed pressure.

Q: How to test air permeability?

A: For nonwoven fabrics, air permeability is measured using the Frazier test method in accordance with standard test methods such as ASTM D737 and DIN 53887. The airflow per unit area through the sample is measured at a specified differential pressure, usually about 200 Pa.

Q: What is the standard for gas permeability test?

A: Relating standard is ASTM D 1434 (V method). Differential pressure method has a good universality for testing gases. With the theoretical support of film technology, vacuum method has been used as the basic method in gas permeability testing and it is adopted by most of the scientific research institutions.

Q: What is the formula for permeability of a gas?

A: In order for permeability to be independent of the permeating fluid and hence solely a property of the porous medium, it has to be multiplied by the viscosity (μ) of the fluid. The resulting quantity is called the specific permeability (K). Thus for liquids, Kl=klμ; and for gases, Kg=kgμ.

Q: How do you perform a permeability test?

A: In this test, water is forced, by a falling head pressure, through a soil specimen of known dimensions and the rate of flow is determined. This test is used to determine the drainage characteristics of relatively fine-grained soils and is usually performed on undisturbed samples.
