Product Feature And Application

High-throughput gas permeability tester suitable for food, pharmaceuticals, medical devices, daily chemicals, agriculture, electronics, and sustainable packaging industries, the gas permeability tester for plastic film also can evaluates the gas transmission performance of 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).

Three Chamber Gas Permeability Tester features a unique integrated design with three independent test cavities. These cavities can operate simultaneously and independently, allowing for parallel testing. Compared to traditional single-chamber instruments, this design boosts testing efficiency by up to 300%. It is capable of testing three identical or different samples in a single run, significantly reducing waiting times in both R&D and quality control processes. This makes it ideally suited for high-throughput application scenarios.
