Product Description:

This instrument is based on the cup method, and is professionally applicable to the water vapor transmission rate test of film specimens.

Principle:

Under a certain test temperature, a constant humidity difference is generated between two sides of the test specimen. The water vapor permeates through the specimen and into the dry side. By measuring the weight changes of the test dish in different time, water vapor transmission rate and other parameters can be obtained.

Test Standards: ISO 2528, GB 1037, GB/T 16928, ASTM E96, ASTM D1653, TAPPI T464, DIN 53122-1, JIS Z0208, YBB 00092003

Product Features:

●The built-in high-resolution load cell provides excellent system sensitivity under the premise of ensuring high precision.

●Wide range, high precision, built-in automated temperature and humidity control system

●Standard purging wind speed ensures constant humidity difference between inside and outside of the permeable cup.

●Automatically zero clear before weighing to ensure the accuracy of each weighing.

●The system adopts cylinder lift mechanical structure design and intermittent weighing measurement method, which effectively reduces the system error.

●Equipped with quick access calibration port for temperature and humidity.

●Provide two quick calibration methods of standard film and standard weight to ensure the accuracy and versatility of test data.

●Precise mechanical design not only ensures the ultra-high precision of the system, but also greatly improves the detection efficiency.

●All 3/6 moisture permeable cups can be tested independently, the test results are displayed independently.

●Dual control: large size touch screen and PC, without PC, use touch screen can carry out the test perfectly. 

●Support storage of test data in multi-format, which is convenient for data import and export.

●Support convenient historical data query, comparison, analysis and printing and other functions.
