Water vapor transmission rate tester ISO 2528, ASTM E96, ASTM D1653

Model: BZ-WVTR
Standards
GB/T 1037, GB/T 16928, ISO 2528, ASTM E96, ASTM D1653, TAPPI T464,DIN 53122-1,JIS Z0208,YBB 00092003
 
This water vapor transmission rate tester is suitable for measuring the water vapor transmission rate of plastic films, composite films and other films, sheet materials, and medical and building materials.  The test is based on the cup method.
 
Features
Weighing method test principle, intermittent weighing that meets the requirements of the standards, the system is automatically cleared before each measurement to ensure the unity and accuracy of the data
High-definition LCD touch screen, more intuitive in sight and easier operation
One sample is tested in a single test, the process is fully automated, the lifting and weighing of the moisture permeable cup is controlled by the cylinder, and the data is accurate and reliable
Innovative circulating dehumidification system, built-in vacuum pump, effectively prevent the formation of humidity gradient above the moisture permeable cup, ensure accurate test
Wide range, high precision, automatic temperature and humidity control,  meeting various test conditions.
Test results support multi-format storage and data output, including test report Excel, cloud sharing
Provide standard weight quick calibration mode, weighing system to ensure the accuracy of test data
Complies with the third-level authority of GMP users
Can carry out single and group statistical analysis of test results
With ISP online control and upgrade functions, the test function can be changed remotely as required
Special computer communication software, real-time display of test, data analysis and processing, data storage.
