Product Application

This instrument is suitable for the determination of water vapor transmission of plastic film, aluminum foil plastic film, waterproof material, metal foil and other high barrier materials. The bottle, bag and other containers are also measurable.

                                                    

Standards

This test instrument conforms to the following standards:

ISO 15106-3GB/T 21529DIN 53122-2YBB 00092003.

                                                    

Principle

Using the principle of electrolytic detection sensor method, nitrogen gas with a certain relative humidity flows on one side of the material after humidification, and dry nitrogen flows on the other side of the material with a certain flow. Due to the difference of humidity gradient, water vapor will spread from the high wet side through the membrane to the low wet side. On the low wet side, the water vapor through the sample is carried to the sensor by the flow of dry nitrogen, the electrolytic sensor will produce equal proportion of electrical signals for the water molecule electrolysis of the sample. Through the analysis and calculation of the electrical signals of the sensor, the water vapor transmission rate of the sample and other parameters can be calculated accurately.

 

Product Feature

Ÿ   Imported micro moisture electrolysis sensor, flow controller, valve, pipe connectors.

Ÿ   Patented pipe flushing technology speeds up testing and makes testing more efficient.

Ÿ   Professional piping system to ensure the cleanliness of carrier gas.

Ÿ   PA level micro current measurement technology, advanced precision measurement.

Ÿ   No mechanical knob gas flow adjustment, sample gas and carrier gas flow are fully automated, and operation is more convenient and quick.

Ÿ   Unique installation technology of anti-side leakage seal of sample to enhance sample seal.

Ÿ   Patented fogless humidifier, fully automatic precision control of humidity on the high wet side.

Ÿ   The temperature control technology of pure semiconductor can be heated or cooled at will, with high control accuracy and stable and reliable system.

Ÿ   Whole-process monitoring, automatic recording, adjustable sampling rate, automatic repeat testing, automatic power cut save function.

Ÿ   The test process can be fully monitored. Powerful graph curve function, easy to compare test and analysis.

Ÿ   Automatic test: set test parameters, and the test will be conducted automatically after the test is started, and the test results will be automatically judged and saved.

Ÿ   Host software has encrypted database system, data can be exported, data storage, inquiry, printing, and other functions. Through the analysis of historical data, it is easy to grasp the historical trend of the product.

Ÿ   High efficiency test, low nitrogen consumption, can be tested and verified by national first-level standards.

Ÿ   The system is capable of self-test to avoid continuous testing under fault conditions.

Ÿ   Gas flow monitoring, automatic alarm when there is little or no gas.

Ÿ   The computer software fully complies with the requirements of GMP computerized system, and has the functions of user management, permission management, data audit and tracking.
