Products Specifications
This instrument is used to test the water vapor transmission rate (WVTR) of thin film materials by the cup method, applicable for testing of multipe kinds of thin film, nonmetal sheet, paper and paperboard, textiles, nonwoven materials etc.
Standards
ISO 2528, GB 1037, GB/T 16928, ASTM E96, ASTM D1653, TAPPI T464, DIN 53122-1, JIS Z0208, YBB 00092003
Features
♦Gas cylinder lifting structure design and periodically weighing method to reduce system errors
♦ Six distinct or equivalent specimens can be tested individually with independent test results in one operation.
♦ Standard air velocity can effectively prevent the formation of moisture gradient.
♦ Wide range and high-precision of automatic temperature and humidity control to support various combinations of non-standard test conditions
♦ Convenient fast-access calibration ports for temperature and humidity.
♦ Controlled by computer and automatic test process.
♦ The test report can be saved and provided in multiple formats,including Excel, database,etc.
♦ Reference film or standard weight for fast and accurate calibration
♦ Equipped with USB port and Common data port for convenient input, output, and data transfer
