Y201d Oxygen Transmission Rate Analyzer

We are offering y201d oxygen transmission rate analyzer.
it is made according to the coulometry theory. Coulometry is a popular international testing theory.
the testing chambers including upper and nether parts, the sample film is fixed between the two chambers, the high pure oxygen (o2) circulate in the upper chamber of the film, and the high pure nitrogen (n2) circulate in the nether chamber of film, the oxygen molecules get through the film and spray to nitrogen in the nether chamber, and brought by the flowing nitrogen to the sensor, and the tester then analyze the oxygen concentration as what the sensor tested and calculate the oxygen permeation quantity. But for the packing containers, the nitrogen circulate in the bottle and the air or oxygen circulate ouside the container .

features
it adopt international advanced electromagnetic temperature control technology, and program step way can control temperature rising and lowering without any external accessory. Temperature control accuracy reach 0.01℃ ;
the humidity control adopt double air humidity control method, humidity control area is large and with high accuracy, humidity flowing stable, it avoid faults such as the big volume and more faults of plugings humidity generator;
it has two calibration methods which are standard gas calibration and standard film calibration. The testing accuracy reach international advanced level, and it ensure the exact testing result.
It has the functions of double cavity pressure control and automatic pressure balance.
It can judge and stop automatically .
it has leakage auto protection function;
the software operation is easy, all testing program is automatic. It records the curves automatically of the permeation rate, oxygen concentration, humidity and temperature and so on. And continuous display. It can monitor the mutual influence between the parameters, and it can monitor the testing process.
The functions are independent modules. The functions of testing , baselines and calibration and so on are independent. It has good ability of data analysis, and its operation is very easy;
it can be used to test high permeability shaped film ( such as contact lenses etc.) with additional testing fixture .
10. It can also be used to test the oxygen permeability of packaging bags or bottles with special fixture.
Configuration
one host computer , one set of special testing software, one pair if cables, one sample cutter, 1/8 inch copper tube 5m .
