- Characteristics:
- Electrolytic method, computer controls, high accuracy and test automatically.
- Highly sensitive, accurate and reliable test data.
- Adjustable test temperature and humidity, easy to fulfill different test conditions.
- System generates test environment independently, no requirements about lab conditions.
- LCD display, test data is clear at a glance.
- World-famous brand elements with stable and reliable performance.
- Friendly human-equipment interaction, easy to operate.
- RS-232 port communication, professional software support, perspicuous test process.
- Functions of data store, research, print, plot and communication.
- Structure:
- It is made up with mainframe and outer circulate controller. Mainframe implements specimen test and outer circulate controller supply test conditions.
- Principle:
- Place the specimen between dry and humid chambers, saturated water vapor will transmits through specimen from the upper chamber to the lower chamber and then be carried to the sensor, which generates electrical signal at the same time. Determine the mass of water vapor transmission and water vapor transmission rate by analyzing and calculating the sensor’s electrical signal.
- Test procedure
- The relationship between pressure and time will be displayed on the screen of the computer in real time after test is started and permeation time will be calculated automatically according to permeation ratio. Test will stop when intervened by users or test results are up to the default. The system will decide whether to print test results or operate other data process according to users’ requirements.
