Product Description GTR-G3 O2, N2 and CO2 Gas Transmission Rate Tester(Differential pressure method)GTR-G3 O2, N2 and CO2 Gas Transmission Rate Tester is based on the differential pressure method, and is professionally applicable to the determination of gas transmission rate (GTR) as well as solubility coefficient, diffusion coefficient and permeability coefficient of plastic films, composite films, high barrier materials, sheeting, aluminum foils, rubber, tire and permeable membrane.Advanced TechnologyThe three permeation cells are completely independent, and can test three identical specimens or distinct specimens simultaneouslyEquipped with imported high-precision vacuum sensor and pressure sensor ensure the test accuracyWorld's first advanced water circulated temperature control system, realized temperature auto control and wider temperature rangeIndependent temperature control for upper/lower chamber and electrolytic sensor, which ensures the accuracy of the test resultsSelf-developed airtight piping system reduces system errors and makes test results more accurateUnique sample anti-leakage structure design, ensure the seal stability of samplesAutomatic pressure holding function, which can adjust the pressure of the upper chamber in real time to ensure the constant pressure difference between the upper/lower chambers during the test7" color touch screen, with professional operating system, the test process is completed the results are displayed automaticallyWith high-speed vacuuming capability, more thorough degassing, short test cycle and high efficiencyHigh-end Configuration Two test modes: proportional mode and standard modeThe system has self-checking capability to ensure that the equipment is in normal test state at any timeGas transmission rate, solubility coefficient, diffusion coefficient and permeability coefficient of the specimen could be obtained at one operationTest range could be extended based on requirements to test the materials with low permeabilityImported components make the operation of the instrument more stable and reliableReference film for fast calibration to ensure accurate and universal test dataWith automatic save function after power failureStandard RS232 port for convenient data transferThe whole testing process is monitored, automatically recorded, and can be reproduced in the whole processThe software is equipped with data traceability, which can realize functions such as multi-level authority management, audit trail, electronic signature, etc., which meets the requirements of GMP (optional)Test PrincipleThe pre-conditioned specimen is mounted in the gas diffusion cell as to form a sealed barrier between two chambers. The lower-pressure chamber is firstly evacuated, followed by the evacuation of the entire cell. A flow of gas is thereafter introduced into the evacuated higher-pressure chamber and a constant pressure difference is generated between two chambers. The gas permeates through the specimen from the higher pressure side into the lower side. The gas permeability and other barrier properties of the specimen can be obtained by monitoring the pressure changes in the lower chamber.ApplicationsBasic ApplicationsFilmsIncluding plastic films, plastic composite films, paper-plastic composite films, coextruded films, aluminized films, aluminum foils, aluminum foil composite films and many othersSheetingIncluding engineering plastics, rubber and building materials, e.g. PP, PVC and PVDCExtended ApplicationPetrochemicalIncluding transportation pipelines, such as MDPE plastic CO2 testingVarious GasesTest the permeability of various types of gases, e.g. O2, CO2, N2, Air and HeInflammable, Explosive GasesTest the permeability of inflammable and explosive gasesBiodegradable FilmsTest gas permeability of various sorts of biodegradable films, e.g. starch-based biodegradable bagsMaterials for Aerospace UsageTest the Helium permeability of airship gas bagsPaper and Paper BoardTest gas permeability of paper and paper-plastic composite materials, e.g. aluminized paper for cigarette packages, Tetra Pak sheeting, paper bowls for instant noodles and disposable paper cupsPaint FilmsTest gas permeability of substrates coated paint filmsGlass Fiber Cloth and PaperIncluding glass fiber cloth and paper materials, e.g. paint cloth, welding cloth and silicon rubber clothSoft Tube Materials for CosmeticsIncluding various types of cosmetic tubes, aluminum-plastic tubes and toothpaste tubesRubber SheetingIncluding various sorts of rubber sheeting, e.g. car tiresVacuum PackagingIncluding vacuum packaging manufacturing sheets that are easily susceptible to gas oxidation and corrosion, such as electronic products, such as consumable sensors, etc.Technical SpecificationsSpecificationsGTR-G3Test Range 0.05~50,000 cm3/m2·24h·0.1MPa (standard volume)At least 500,000 cm3/m2·24h·0.1MPa (extended volume)Number of Specimens3Number of Sensors3Test ModeThree chambers independentVacuum Resolution0.1 PaVacuum Degree of Test Chamber<20 PaTest Temperature5°C~95°C ±0.1°C (dry gas at standard atmospheric pressure)Temperature Accuracy±0.1oCTest Pressure-0.1 MPa ~ +0.1 MPaGas Supply Pressure0.1 MPa~0.8 MPaTest GasO2, N2 and CO2 (outside of supply scope)Carrier Gas InterfaceФ6Vacuum Pipe Diameter1/4"Correction MethodStandard film calibration, external calibration of vacuum sensorSpecimen Thickness≤3mmSpecimen SizeΦ97 mmTest Area38.48 cm2Instrument Dimension740 mm (L) x 415 mm (W) x 430 mm (H)Power SupplyAC 220V 50HzNet Weight50 kgStandardsASTM D1434, GB/T 1038, YBB 00082003, ISO 2556, ISO 15105-1, JIS K7126-AConfigurationStandard configuration: Instrument, vacuum pump, vacuum pipe, gas tube, pressure regulator, sampler, vacuum grease, reference film, temperature controlling device.Optional configuration: Computer, container testing fixture, sampler blades, vacuum grease, filter paper, humidity generator.Note: Customer need to prepare testing gas.FAQAre you a manufacturer or trading company?We are the manufacturer and trading combo, which specialize in material testing instruments such as plastic package, medical device, facial mask, protective clothing and pharmaceutical package, etc. We located in Jinan, Shandong, China.Do you have any certificate?We have obtained CE certificate, passed ISO 9001, IPMS management system certificates, and have 18 utility model patents and 4 software copyright certificates.How about the installation?The user's manual specifies the installation requirements with details.
