Water Vapor Permeability Testing Equipment for Precision Material Analysis

DESCRIPTION / TECHNICAL SPECIFICATIONS

Introducing a fundamental testing instrument for research, development, and quality control across numerous industries: the Water Vapor Permeation Tester. This device is specifically engineered to measure the water vapor transmission rate (WVTR) of a wide array of packaging materials. From the food, pharmaceutical, and cosmetics industries to flexible packaging materials like plastic films, barrier materials, aluminum foils, and PVC sheets, this instrument provides crucial quantitative data to ensure product integrity and shelf life. Its testing procedures fully comply with leading international standards, including ASTM E96, ASTM D1653, ISO 2528, and TAPPI T464, making it a reliable and globally recognized tool.

Utilizing the proven weighing method principle, this instrument detects weight changes to determine WVTR with exceptional accuracy, down to 0.001 g/m2·24h. The testing process occurs within a chamber where temperature and humidity are precisely controlled. By creating a vapor pressure differential across the two sides of a sample, the rate of water vapor permeation is accurately measured. The instrument boasts a very wide measurement range from 0.02 to 10000 g/m2·24h and can control temperature from 15℃ to 45℃ with ±0.1℃ accuracy and humidity with ±2%RH accuracy, ensuring stable and replicable test conditions for consistent results.

The operation of this device is designed for maximum user-friendliness and efficiency. Equipped with a 240,000 true color high-resolution touch screen, the instrument operates independently without the need for an external computer. All test parameters, the status of each curve, and data are displayed in real-time. The testing process is fully automatic, supported by high-precision sensors with over-range protection for continuous and accurate data collection. Featuring superior components and a multi-level security design, this instrument guarantees reliable and safe operation at all times.

Flexibility is a key advantage of this instrument. Calibration can be easily performed using two methods: weights and standard film, ensuring long-term accuracy. The advanced accompanying software supports versatile operating languages and can be expanded to control ten or more test chambers simultaneously. CE, UL, and FCC certifications serve as a testament to its commitment to international quality and safety standards, providing peace of mind for every user in any laboratory worldwide.

Investing in this water vapor permeation tester is a strategic move to ensure your product quality meets the highest standards. With its ability to deliver accurate, fast, and reliable data, companies can accelerate new product development, verify the quality of materials from suppliers, and ensure every package provides optimal protection. It is the definitive solution for professionals in quality control, research, and academia who require indisputable WVTR data.
