Differential Pressure Method Gas Transmission Tester N530A 2.0 Introduction N530A 2.0 Gas Permeability Tester is based on the differential pressure method and is designed and manufactured in accordance with standards such as GB/T 1038 and ISO 2556. It employs a high-precision pressure sensor and automatic differential pressure maintenance technology, ensuring high testing accuracy. It is suitable for testing the gas permeability of films, sheets, paper, packaging materials, and related materials in the food, pharmaceutical, medical device, daily chemical, and photovoltaic electronics industries, providing a wide range and high-efficiency gas permeability detection for high, medium, and low gas barrier materials. Test principle The N530A 2.0 gas permeability tester uses the differential pressure method. The prepared sample is placed between the upper and lower chambers. A vacuum pump is used to evacuate the entire gas path system. Then, one atmosphere of test gas is added to the upper chamber to create a constant Add.: No. 3, Linjiang Road, Huangpu District, Guangzhou, Guangdong Province, China

pressure difference between the upper and lower chambers. Under the influence of the pressure gradient, the gas permeates through the membrane from the upper chamber to the lower chamber. The system can calculate the gas permeability and other barrier performance parameters of the sample by analyzing the pressure change in the lower chamber. high pressure chamber limit outflow valve Automatic adjustment of the upper chamber pressure to maintain a pressure difference of 100 kpa between the upper and lower chambers at all times. After vacuuming Initial pressure under 27KPA Working principle Chinese...

Packaging Testing Instruments • Patented core technology for efficient and accurate testing Imported high-precision vacuum sensor, integrating silicon piezoresistive chip and temperature compensation technology, achieves a full-scale drift of only 0.01% reading/°C, enabling continuous full-scale measurement and avoiding pressure jump blind spots during vacuum pumping. Constant temperature control reduces thermal drift, achieving repeatability <±0.2% FS. Patented automatic differential pressure maintenance technology automatically maintains the pressure difference across the sample (adjustable...

A brand-new pneumatic gas path control system with automatic clamping and one-button sample locking is convenient, labor-saving, and provides superior sealing performance.  Meets high-throughput, wide-range, and highly applicable testing requirements. The instrument is equipped with three chambers, supporting simultaneous testing of three identical or different samples. Operation is independent, data is independent, and testing efficiency is high. It has a wide testing range, with a lower testing limit as low as 0.01 cm³/(m²·24 h·0.1 MPa), meeting the testing needs of various high, medium, and...
