China Y204D Oxygen Water Vapor Dual Mode Permeabilty Tester

Y204D Oxygen & Water Vapor Dual Mode Permeation Equipment
Function
Y204D can be used to do high-precision oxygen permeability and water vapor permeability testing of film or sheet at the same time;
It adopts Coulometry theory for oxygen permeability test, and adopts international advanced electrolytic process theory for water vapor permeability test;
It is applicable for testing the oxygen transmission property and water vapor transmission property of plastic film, sheet and plastic bottles and bags etc. Packaging containers in air or pure oxygen.
Standard
GB/T 19789-2005, ASTM D 3985, ASTM F2622, ASTM F 1927, ASTM F 1307, ISO 15105-2, YBB00082003, DIN 53380-3, JIS K-7126-B. GB/T 21529, ISO15106-3, YBB 00092003, DIN 53122-1
Principle
It adopts Coulometry 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 blowing nitrogen to the sensor, so, the tester then analyze the oxygen concentration as what the sensor tested and calculate the oxygen transmission value. But for the packing containers, the nitrogen circulate in the bottle and the air or oxygen circulate outside the container
For water vapor permeability testing;
It is made according to the electrolytic process theory;
The testing chambers including upper and nether parts, the sample film is fixed between the two chambers, water vapor circulate in the upper chamber of the film, and dry gas circulate in the nether chamber of film, water molecules get through the film and spray to dry gas in the nether chamber, and brought by the blowing gas to the sensor, so, the tester then analyze the water vapor concentration as what the sensor tested and calculate the water vapor transmission value.
Features
1. It can be used to test feeble oxygen permeability and feeble water vapor permeability. Oxygen permeability test according to the Coulometry theory and water vapor permeability test according to electrolytic process theory. And the chambers can be used to do oxygen permeability test or water vapor permeability test independently.
2. The chambers can be added to 30 chambers. Some can be used to test oxygen permeability and some to test water vapor permeability.
3. Use international advanced electromagnetic temperature control technology, so rising and lowering temperature can be easily operated by program steps without any external accessory. Temperature control accuracy reaches 0.01º C
4. The humidity control adopt double air humidity control method, humidity control area is large and with high accuracy, humidity flow is stable, it avoid faults such as the big volume and more faults of plugging humidity generator;
5. It has two calibration methods of standard gas calibration and standard film calibration. The testing accuracy reach international advanced level and it ensure the exact testing result.
6. It has the functions of double cavity pressure control and automatic pressure balance.
7. It can judge and stop automatically;
8. It has leakage auto protection function;
9. 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;
10. 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;

Test Range 0.02 ~ 16,500 cm3 / m2/ day (with large the test chamber, the max testing range can reach 260000cm3/m2·day)Test Accuracy 0.001 cm3 / m2/ dayHumidity Range 0.02 ~ 10,000 g/m2·24hHumidity Accuracy 0.001g/m2·24hTemperature Control Range 5~50°CTemperature Accuracy ±0.01°CHumidity Range 0%RH, 5~95%RH, 100%RHHumidity Accuracy ±1%RHSpecimen Size Φ80mm Test Area 50.24cm2Specimen Thickness ≤2mmNumbers of Specimen 4 piecesInlet Size 1/8 metal pipePressure 0.2~0.3MPaTesting environment room temperature (Standard conditions 23°C)
