G2/131 Gas Permeability Tester

Product catalog summary

Overview
The G2/131 Gas Permeability Tester by Labthink Instruments Co., Ltd. is designed to measure the gas transmission rate, solubility coefficient, diffusion coefficient, and permeability coefficient of various materials such as plastic films, composite films, and aluminum foils. It operates using the differential pressure method and can test three specimens simultaneously, adhering to international standards like GB, ISO, and ASTM.

Key Features

Proportional and standard test modes with easy parameter settings.
Simultaneous testing of three distinct or identical specimens.
Capability to test a wide range of gases, including hazardous ones (customization required).
Data fitting function for calculating gas permeability at different temperatures.
High-quality components ensure reliable performance.
Embedded computer control system for enhanced data management and operation.
Four USB ports and dual Internet ports for data transmission.

Intelligent Software

User-friendly interface with intelligent data management.
Supports Lystem™ Lab Data Sharing System for uniform data management.
Status monitoring and sensor calibration reminders.
Embedded help documents and multi-level account control.

Test Principle
The specimen is mounted in a gas diffusion cell, creating a sealed barrier between two chambers. A pressure difference is established, and gas permeates through the specimen. The permeability is determined by monitoring pressure changes.

Applications

Basic: Films, sheeting, and various composite materials.
Extended: Various gases, including inflammable and poisonous gases, biodegradable films, aerospace materials, and more.

Technical Specifications

Test Range: 0.05 ~ 50,000 cm³/m²·24h·0.1MPa.
Temperature Range: 15°C~ 55°C with ±0.1°C accuracy.
Humidity Range: 0%RH to 100%RH with ±1%RH accuracy.
Specimen Size: Φ97 mm with a test area of 38.48 cm².
Instrument Dimensions: 690 mm (L) x 350 mm (W) x 360 mm (H).
Power Supply: AC (85 ~ 264)V (47 ~ 63)Hz.

Configurations

Standard: Mainframe, software, monitor, keyboard, mouse, sample cutter, vacuum grease, filter paper, and vacuum pump.
Optional: Additional blades, vacuum pump oil, humidity generator, and printer.
