N530 2.0 is based on the test principle of differential pressure method, It's designed with reference to GB/T 1038, ISO 2556 and other standards. Adopt high-precision pressure sensor and automatic pressure difference keeping technology, high test accuracy. It is suitable for the gas permeability test of films, sheets, papers, packages and related materials in the fields of food, medicine, medical equipment, daily chemicals, photovoltaic electronics, etc. It provides a wide range and high-efficiency gas transmission rate test of high, medium and low gas barrier materials.
Test Principle
According to 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 experimental gas of an atmospheric pressure to the upper chamber to form a constant pressure difference between the upper and lower chambers. Under the pressure gradient, the gas permeates from the upper chamber to the lower chamber through the membrane, then the system can calculate the barrier performance parameters such as the gas permeability of the sample through the pressure change of the lower chamber.
