DRK311 gas permeability tester, also known as gas transmittance tester or breathability meter, is an instrument used to detect the permeability of gases (such as oxygen, ammonia, carbon dioxide, etc.) in materials.
Gas permeability tester is mainly based on the principle of differential pressure test. When testing, the pre-treated sample is placed between the upper and lower test chambers and clamped. First, the low-pressure chamber (lower chamber) is vacuumed, and then the entire system is vacuumed. When the specified vacuum degree is reached, the lower chamber of the test is closed, and a certain pressure of the test gas is filled into the high pressure chamber (upper chamber), and a constant pressure difference (adjustable) is ensured on both sides of the sample. In this way, the gas will permeate from the high-pressure side to the low-pressure side under the action of the pressure difference gradient. By monitoring the internal pressure of the low pressure side, the barrier parameters of the tested samples can be obtained.
Gas permeability tester is widely used in food, medical packaging and other industries, specializing in plastic film, composite film, high barrier material, sheet, metal foil, rubber, tire air tightness, permeable film and other materials of gas permeability, solubility coefficient, diffusion coefficient, permeability coefficient measurement.
DRK311 Gas permeability tester Features:
1, imported high-precision vacuum sensor, high test accuracy;
2, three independent test chamber, can simultaneously test three kinds of the same or different samples;
3, precision valve pipeline components, strong sealing, high-speed vacuum, desorption, reduce test error;
4, to provide proportional and fuzzy dual test process judgment model;
5, built-in computer host, built-in high-performance motherboard, the system adopts computer control, the whole test process is automatically completed;
6, advanced software architecture design, networking, data sharing, remote diagnosis, so that customers can quickly get test reports;
7. The special wrench can also ensure the consistency of the compression force of the upper chamber of the test, avoiding the different compression force caused by the difference in the strength of the tester;
8, the software follows the GMP permission management principle, with user management, permission management, data audit tracking and other functions;
9. Patented grease coating technology, hygienic, accurate and efficient. The core patented structure is designed to reduce the vacuum time and thus shorten the test time.
