- Characteristics
- Four chambers test independly with highefficiency.
- Dynamic relative humidity measurement, easy to test.
- Blank test, independently four test chambers, groups test.
- Dispense with weigh, high ability of intervention resistance, accurate data.
- Test full automatically, dispense with manual intervention.
- Digital P.I.D. temperature control system.
- Professional software, display test data automatically.
- Database storage mode.
- Adjustable analyzing point and range, easy to realize nonstandard test.
- Computer controls and monitors automatically, easy to operate.
- Principle
- Place the specimen between the dry and humid chambers, the sensor located in the test chamber analyzes the change of humidity and traces the time from lower limited value preset to upper limited value preset. Determine the mass of water vapour transmission and water vapour transmission rate by continuous test and analysis.
- Operation characteristics
- Before test, just input parameters of pre-heating time, test temperature, and so on. Tester will finish the test automatically and print out test results.
- W VTR under different conditions got, one group or multi-groups test conditions set according to actual requirement of packaging materials.
- Easy to clamp specimen and maintenance.
- Four different materials can be tested at one time.
- Computer enables the functions of storage, researching, printing, and curve displaying.
