Differential pressure method Gas Permeability Analyzer

Differential pressure method Gas Permeability Analyzer N530 2.0

Product introduction

This product is based on the test principle of the differential pressure method, and is designed and manufactured with reference to GB/T 1038, ISO 2556 and other standards. Using high-precision pressure sensor and automatic differential pressure maintaining technology, the test accuracy is high. It is suitable for the gas permeability test of films, sheets, paper, packaging and related materials in the fields of food, medicine, medical equipment, daily chemicals, tovoltaic electronics, etc. It provides a wide range of high, medium and low gas barrier materials. , High-efficiency gas transmission rate detection.

Test principle

The N530 2.0 gas permeability tester adopts the principle of differential pressure method. Place the processed sample between the upper and lower chambers, use a vacuum pump to evacuate the entire gas circuit system, and then add an atmosric pressure experimental gas to the upper chamber to form a constant pressure difference between the upper and lower chambers. Under the action of the pressure gradient, the gas permeates from the upper cavity to the lower cavity through the film, and the system can calculate the barrier performance parameters such as the gas permeability of the sample through the pressure change of the lower cavity.
