Wide range and high-precision of temperature and humidity control to support various combinations of non-standard test conditions. Standard, proportional, and continuous testing modes facilitate to test different materials with distinct water vapor permeability.
Embedded computer control system provides safer and more reliable data management as well as test operation. Three diffusion cells are integrated in one instrument with lower space occupancy rate and higher test efficiency. Intelligent designs for test result evaluation, sensor calibration reminding, tracing or managing operation record provide a safe and easy operation environment.
Food and Beverage Packaging: Barrier performance directly affects product freshness. WVTR testing helps confirm whether your film or laminate keeps moisture out long enough to meet shelf-life expectations. That means fewer recalls and more consistent product quality.
Pharmaceuticals and Nutraceuticals: Capsules, tablets, and powders often degrade in humid conditions. With WVTR testing, you validate the protective properties of your blister packs, sachets, or bottles—essential for both patient safety and regulatory compliance.
Consumer Electronics and Optoelectronics: Moisture can quickly degrade sensitive electronic components, especially in wearables or OLED displays. For these applications, WVTR targets can reach 10⁻⁶ g/m²/day, requiring highly sensitive instrumentation. Getting this right ensures device longevity and reduces failure rates.
Building and Construction Materials: Vapor retarders, roofing membranes, and insulation systems are all tested for water vapor permeability. Understanding WVTR helps you balance moisture resistance with breathability, key for energy efficiency and structural health.
Material Compatibility of WVTR Tester
No two industries are the same. What works in one industry may not work in another. This is especially true concerning the type of materials industries test. Some industries only test films of low thickness. Others test high-thickness materials like foils and metal sheets.
Our wvtr testing machine should be compatible with various materials, whether flexible films, foils, or coatings. Ultimately, a machine that accommodates a wider range of materials provides a broader versatility for its use in diverse applications.
