Industrial Machinery & Equipment

Test Principle Firstly submerge the specimen in the water in the vacuum chamber, and then evacuate the vacuum chamber to form differential pressure between the inside and outside of specimen. The seal property can be obtained by observing the steady progression of bubbles from the specimen or observing how the specimen expands and restores to its original shape after vacuum release. Features Compressed air，pneumatic drive. Wholly automatic, auto vacuum and keep for set time at set pressure, auto stop and return. Can manually pause and stop. LCD display test data and working status. Built-in printer can print report with date.

Application The Leakage tester GB-M2 is designed and manufactured in accordance with the relevant provisions of GB/T15171 Test method for leaks in sealed flexib , le  packages. It is used to detect the sealing condition of plastic packaging bags and containers, and it is applied to used in industries of food, beverage, pharmaceuticals, personal care and so on. Through test can effectively compare and evaluate the sealing technology and sealing performance of packaging parts, and provide scientific basis for determining the relevant technical indicators. It can also be used to test the sealing performance of the specimens after dropping and compressing test. Standards GB/T 15171-1994, ASTM D3078-2002（2013）

Standards: GB 10006, ASTM D 1894-01, ISO 8295, TAPPI 816 Function: By testing the friction efficient number judges the smoothness, uniformity of film, efficiently to prevent it’s smoothness level avoiding the quality defects. Used in packaging industry, membrane industry, inspection agency and so on. Application : *Films Rigid films, shrik films, stretch films, plastic films, plastic composite films, paper-plastic composite films,aluminized films, aluminum foil, aluminum composite films, high barrier films and many others. Eg. PET, OPP, CPP, LDPE, BOPP

Features 1. Accurate and reliable data With The State Certificate for Gradation of the certified Reference Materials and Licence for Manufacturing Measuring Instruments of the state Reference Materials(GBW(E)130541/2)of Gas Permeability Analyzer approved and issued by General Administration of Quality Supervision, Inspection and Quarantine of the P.R.C. Adopting state reference materials to calibrate and verify the instruments, data reliability up to 100%, with universal temperature and humidity calibration interface and test repeatedly, the dispersion of the same sample test data are less than 10%. Ensure the accuracy, universality and authority of test data. 2. Simple operation lProfessional software with simple interface, easy to use and convenient to set test process. lFully-auto operation, one-button test, judge and stop automatically. lProgrammed auto-control, the experiment status display in real time. lReal time curves display of transmission, water vapor concentration, temperature and humidity. The curves with conceal function, support query function for background data. lConfigure with color touch screen, can observe temperature, humidity and transmission without external computer. lProfessional test report; can be exported as PDF. 3. Advanced technology lWorld’s pioneered auto keep pressure difference technology, which can keep pressure difference of two sides of samples automatically (pressure can be adjusted). lTemperature control: International advanced electromagnetic technology, program controlled, automatic temperature rise and fall. Precision 0.01℃. lCarrying cutting-edge ARM controlling system, can run independently without computer. 4. High efficiency lOne independent test chambers with a independent main sensors lWith three different test modes of high, medium and lower barriers, can test films with different barrier property. lMeasurement precise up to 0.01 cm3/(m2·24h·0.1MPa), can test high barrier materials, such as aluminum foil. lBy adding package-testing accessories, can test gas transmission of various containers such as bag, bottle, can and bowl. lCan expand upper limit of test range to 600000 cm3/(m2·24h·0.1MPa). 5. Calibration & Certification lThe instrument supports two methods of reference materials and standard gas to certificate and calibrate; Operation is simple, user only need use certified reference materials for normal testing, and then input the test result into the instrument interface to complete calibration. 6. Reliable and easy-maintenance instrument lImported pressure sensor, with high precise and good performance, can work for a long time. lSensor over-range auto protection. lFunction modularization, easy to maintain.
