Product Details
Product Introduction:
GB/T 16928 Water Vapor Transmittance TesterWVTR-RC6 water vapor permeability tester is a professional, efficient, and intelligent WVTR testing system suitable for measuring the water vapor permeability of various materials such as plastic films, composite films, medical and construction fields. By measuring the water vapor transmission rate, the technical indicators for controlling and regulating packaging materials and other products can be achieved.
Execution standard:
Based on the cup method testing principle, it is a professional water vapor transmission rate (WVTR) testing system for thin film samples, which can detect water vapor transmission rates as low as 0.1g/m2 · 24h; The configured high-resolution weighing sensor provides excellent system sensitivity while ensuring high accuracy.
Wide range, high precision, automated temperature and humidity control, easy to achieve non-standard testing.
The standard blowing speed ensures a constant humidity difference between the inside and outside of the moisture permeable cup.
The system automatically resets to zero before weighing to ensure the accuracy of each weighing.
The system adopts a cylinder lifting mechanical structure design and intermittent weighing measurement method, effectively reducing system errors.
The temperature and humidity calibration socket that can be quickly accessed facilitates users to perform quick calibration.
Provide two quick calibration methods, standard film and standard weight, to ensure the accuracy and universality of the detection data.
The precise mechanical design not only ensures the ultra-high precision of the system, but also greatly improves the detection efficiency.
6 breathable cups can be independently tested without interfering with each other, and the test results are displayed independently.
The large-sized touch screen is user-friendly and efficient, making it easy for users to operate and learn quickly.
● Support multi format storage of experimental data, facilitating data import and export.
● Support multiple functions such as convenient historical data query, comparison, analysis, and printing.

Test principle:
The principle of using the moisture permeable cup weighing method is to create a specific humidity difference on both sides of the sample at a certain temperature. Water vapor passes through the sample in the moisture permeable cup and enters the dry side. By measuring the change in weight of the moisture permeable cup over time, parameters such as the water vapor transmission rate of the sample can be determined.
Execution standard:
This instrument complies with multiple national and international standards: GB/T 1037、GB/T 16928、ISO 2528、ASTM E96、ASTM D1653、TAPPI T464、DIN 53122-1、JIS Z0208、YBB 00092003
