ASTM D1434 Labthink Plastic Film and Rubber Gas Permeability Testing Instrument

Product Overview

Description

 

VAC-V1 Plastic Film and Rubber Gas Permeability Tester is based on the differential pressure method, and is professionally applicable to the determination of gas transmission rate as well as solubility coefficient, diffusion coefficient and permeability coefficient of plastic films, composite films, high barrier materials, sheeting, metal foils, rubber, tires, and permeable membranes.

• Gas transmission rate, solubility coefficient, diffusion coefficient, and permeability coefficient of the specimen could be obtained at one operation
• The instrument comes with two test modes: proportional mode and non-proportional mode
• Test range could be extended based on user requirements to test materials with high permeability
• High precision temperature control to meet different test conditions
• Test results could be easily obtained even at extreme condition by data fitting function, which could fit any temperature
• The instrument could be used to test poisonous, inflammable, and explosive gases (customization required)
• The instrument is controlled by a computer and test process is automatic
• Reference film for fast calibration to ensure accurate and universal test data
• Fast-access calibration port for temperature and humidity, and standard RS232 port for convenient calibration and data transfer
• Support Lystem™ Lab Data Sharing System for uniform management of test results and test reports
