What is Water Vapor Transmission Rate Tester

Water Vapor Transmission Rate Tester, also known as a permeability tester, uses the cup method to measure water vapor transmission rates in films, sheets, and textiles. It creates a humidity gradient across the sample, with weight changes over time determining permeability, adhering to ISO 2528, GB 1037, ASTM E96, and other standards. This ensures reliable performance for packaging, medical, and textile applications.

In packaging, it verifies barrier properties of plastic films and composites. In medical and building sectors, it assesses materials like paper and textiles for moisture control. The tester’s precision helps manufacturers meet diverse regulatory and application needs.

Product Description

Our Water Vapor Transmission Rate Tester is a professional solution designed for accurate water vapor permeability measurement in films, sheets, paper, and textiles. Based on the cup method, it features weigh-based testing, simultaneous testing of up to three samples with micro-motor-controlled lifting, and automated temperature-humidity control. Compliant with ISO 2528, GB 1037, ASTM E96, and other standards, it’s ideal for plastic films, composites, and medical packaging.

With a test range of 0.01~10,000 g/m²·24h, system resolution of 0.001g, and support for samples up to 3 mm thick, it includes automatic zeroing, multi-format data storage (Excel, cloud), and a robust design (620x620x570mm, 97kg). It operates on AC 220V 50Hz with a Φ6mm polyurethane gas interface (user-provided compressed air or dry nitrogen).
