- 所属类别
- 试剂实验设备
- 物化性质
- 采用压差法测试原理，将试样置于上下测试腔之间夹紧，对低压腔抽真空后向上腔充入试验气体，在试样两侧形成恒定且可调的压差。可同时测定试样的气体透过率、溶解度系数、扩散系数和渗透系数，支持氧气、二氧化碳、氮气、空气、氦气等多种气体（易燃易爆气体可定制）。三个测试腔完全独立，可同时测试三种相同或不同的试样；提供比例和模糊双重试验过程判断模式，具备宽范围温度数据拟合功能。系统由计算机控制，试验全程自动完成，真空泵按实验进度自动启停；配备标准膜快速校准功能，保证检测数据的准确性和通用性；配备RS232通用数据接口，方便数据传递。

Product Name:Differential Pressure Gas Permeability Tester
English Name:Differential Pressure Gas Permeability Tester
Aliases:Gas Transmission Rate Tester, Gas Permeability Analyzer, Differential Pressure Gas Permeability Analyzer
Physical Properties:Based on the differential pressure method, the specimen is placed and clamped between the upper and lower test chambers. After evacuating the lower chamber (low-pressure side), the test gas is introduced into the upper chamber (high-pressure side), forming a constant and adjustable differential pressure across the specimen. The instrument simultaneously measures the gas transmission rate, solubility coefficient, diffusion coefficient, and permeability coefficient of the specimen. It supports testing of various gases including oxygen, carbon dioxide, nitrogen, air, and helium (flammable and explosive gases available on request). Three fully independent test chambers allow simultaneous testing of three identical or different specimens, and the system features both proportional and fuzzy test process judgment modes as well as wide-range temperature data fitting functions. The system is computer-controlled with the entire test process fully automated, and the vacuum pump automatically starts and stops according to the test progress. It is equipped with a standard film quick calibration function to ensure the accuracy and universality of test data, and an RS232 universal data interface for convenient data transfer.
Uses:Suitable for gas permeability testing of film materials such as plastic films, composite films, aluminized films, and aluminum foils, as well as sheet materials including engineering plastics, rubber, flexible tubes, paper and paperboard, fiberglass fabrics, aerospace materials, coatings, and biodegradable films. It can be used for barrier property evaluation of packaging materials for food, pharmaceutical, and daily chemical products, providing data support for packaging material selection and quality control.
Technical Specifications:
Test range: 0.05~50,000 cm³/(m²·24h·0.1MPa) (standard), expandable to no less than 500,000 cm³/(m²·24h·0.1MPa)
Vacuum resolution: 0.1 Pa; test chamber vacuum degree: <20 Pa
Specimen size: Φ97 mm; transmission area: 38.48 cm²; number of specimens: 3
Temperature control range: 5℃~95℃, accuracy: ±0.1℃; humidity control range: 0%RH, 2%RH~98.5%RH, 100%RH, accuracy: ±1%RH
Test gases: O₂, N₂, CO₂, etc. (gas source supplied by user); test pressure: -0.1 MPa~+0.1 MPa (custom pressure available); gas source pressure: 0.6 MPa
