Water vapor permeability tester W413 2.0

water vapor transmission ratefor packagingfor photovoltaic modules

Application
W413 2.0 water vapor permeability tester is designed to measure the water vapor transmission rate (WVTR) of films and sheet materials under controlled temperature and humidity conditions.

Applied to

• Plastic films, composite films, aluminum foil, aluminized film.
• Sheets, panels, rubber, ceramics.
• Packaging containers such as glass, bottles, cans, boxes.
• Extended applications: solar panels, LCD films, medical patches.
• Used by inspection bodies, pharmaceutical control institutions, research institutes, packaging manufacturers, food and electronics industries.

Standards

• GB/T 26253-2010
• YBB 00092003-2015
• BS EN ISO 15106-2:2005
• ASTM F1249-2013
• JIS K7129-2008

Features

• Accurate data: Calibrated with state reference materials for validated and authoritative test results.
• Simple operation: Professional software with one-button fully automatic testing, real-time curve display (permeability, flow, voltage, temperature, humidity), background data query and automatic PDF report export; mainframe with color touch screen for standalone operation.
• Advanced control: Electromagnetic program step temperature control (automatic heating/cooling) with 0.1 °C precision; dual-gas flow humidity control (dry and humid gas) with ±1%RH accuracy and stable humidity.
• High throughput: Three independent test chambers with separate sensors to run three identical or different samples simultaneously; high/medium/low barrier test modes; measurement resolution to 0.001 g/(m²·24h) for high-barrier materials.
• Data integrity: Software meets GMP computerized system requirements with multi-level accounts (administrator, instrument admin, auditor, operator), audit trails and change logs.
• Reliable components: Imported infrared sensor with high precision and long life, sensor over-range protection and modular design for easy maintenance.
