EVA co-extruded film oxygen permeability tester OX2-231

EVA co-extruded film oxygen permeability tester OX2-231: Oxygen Permeability Tester is a professional film sample and container specimens for oxygen permeability tester for plastic films, laminated films, sheets oxygen transmission rate test timber and plastic bottles, plastic bags and other packaging containers. Professional and technical characteristics of EVA co-extruded film oxygen permeability tester OX2-231 instruments: three-chamber mean, a single test can give an average of three tests to support the film and container double test mode (container test accessories are sold separately) Can be used with thermostatic control devices and humidity controller, to meet the requirements of different test conditions (devices sold separately) provides a standard film for quick calibration test data to ensure the accuracy and versatility of the system is controlled by microcomputer with LCD screens, menus style interface, and PVC panel, user-friendly quick, intuitive view the test data, the results, and the test curve off automatic recovery, ensure data security with mini printer and RS232 universal data interface for data output and delivery support Lystem? between the use of the principle of equal pressure method to test the pre-treatment sample a good grip on the test chamber: Laboratory Data Sharing System, unified management of test results and test reports EVA co-extruded film oxygen permeability tester OX2-231 test principle , the flow of oxygen in the film on one side, the other side of the flow of nitrogen in the film. Oxygen diffusion through the membrane to the other side of the nitrogen, the nitrogen flow was carried to the sensor. Was analyzed by measuring the oxygen concentration sensor to calculate the oxygen transmission rate and other parameters. For the packaging container, the nitrogen flow in the vessel, oxygen is enclosed in the outer container. EVA co-extruded film oxygen permeability tester OX2-231 implementation of the standards: ISO 15105-2, GB / T 19789, ASTM D3985, ASTM F2622, ASTM F1307, ASTM F1927, JIS K7126-2, YBB00082003 EVA co-extruded film oxygen permeability number of samples 0.01 ~ 1000 cm3 / m2 · d (conventional) 0.1 ~ 10,000 cm3 / m2 · d (Optional):: Over meter to OX2-231 technical parameters: ① film test technical indicators: test range from 1 to 3 Resolution: 0.01 cm3 / m2 · d Temperature range: 15 ℃ ~ 55 ℃ (optional) Temperature accuracy: ± 0.1 ℃ Humidity control range: 0% RH, 15% RH ~ 90% RH, 100% RH (another purchase) Wet control accuracy: ± 1% RH test gas: O2, air, etc. (gas source user-owned) test area: 50 cm2 sample thickness: ≤3 mm (other thickness requirements can be customized) Sample size: 108 mm x 108 mm carrier gas: 99.999% purity nitrogen (gas source user-owned) Air pressure: ≥0.28MPa interface Size: 8-inch metal pipe Dimensions: 670mm (L) × 410mm (W) × 310mm (H) Power Supply: AC (85 ~ 264) V (47 ~ 63) Hz Weight: 48kg ② container testing (optional): Test range: 0.0001 ~ 10 cm3 / pkg · d (conventional) number of samples: 1 to 3 Resolution : 0.0001 cm3 / pkg · d control humidity range: 0% RH, 15% RH ~ 90% RH, 100% RH (optional) Wet control accuracy: ± 1% RH test gases: O2, air, etc. (gas source user Preparation) Sample size: 100% O2 Test: less than Ф120 mm, a height of less than 360 mm open test (air): Size Any bottle: bottle inside diameter> Ф8 mm Mouth OD <Ф42 mm (conventional) bag, box: Accessories Support Carrier gas: 99.999% purity nitrogen (gas source user-owned) Air pressure: ≥0.28MPa interface Size: 8-inch metal pipe Dimensions: 670mm (L) × 410mm (W) × 630mm (H) Power : AC (85 ~ 264) V (47 ~ 63) Hz Weight: 50 kg EVA co-extruded film oxygen permeability tester OX2-231 instrument configuration: Standard configuration: host, micro-printer, specialized software, precision pressure nitrogen bottle valves, oxygen bottles precision valve Option: thermostatic control device and humidity controllers, sealed container test accessories, container cover test Note: This machine imported gas source for the 8-inch metal pipe; gas source users themselves.
