WVTR-E1 Water Vapor Transmission Rate Tester
WVTR-E1 Water Vapor Transmission Rate Tester
The WVTR-E1 Water Vapor Transmission Rate Tester by Pubtester Instruments Co., Ltd. is designed to measure the water vapor transmission rate of barrier materials using the electrolytic sensor method, conforming to ISO 15106-3 standards. It is suitable for testing materials in various industries including food, pharmaceuticals, and electronics.
Product Features
- Advanced technology with high precision micro vapor electrolytic sensor for improved accuracy and stability.
- Automatic gas flux control and temperature control systems for stable testing processes.
- Self-developed pipeline gas system and anti-side leakage technology for accurate results.
- Automatic power failure saving, real-time monitoring, and efficient testing with low nitrogen consumption.
- Professional software with intuitive interface, data analysis, and reporting functions.
Test Principle
The specimen is placed in a diffusion cell divided into dry and controlled-humidity chambers. Dry nitrogen sweeps the dry side, carrying water vapor to the electrolytic sensor, where electrical signals are generated and analyzed to determine the water vapor transmission rate.
Applications
- Basic Applications: Testing films, sheets, paper, and packages for water vapor transmission rates.
- Extended Applications: Includes package closures, LCD displays, solar back-sheets, pipes, blister packs, and medical films.
Technical Specifications
- Test Range: Film (0.001~50 g/m²·24h), Container (0.00001~0.25 g/pkg·24h).
- Sensor Accuracy: 0.001 g/m²·24h.
- Temperature Control: 15°C to 60°C with ±0.1°C accuracy.
- Humidity Control: 0% RH to 100% RH with ±1% RH accuracy.
- Carrier Gas: 99.999% high-purity nitrogen, flow rate of 100 mL/min.
- Dimensions: 740mm x 415mm x 430mm, Weight: 50Kg.
Standards and Configuration
The tester complies with ISO 15106-3, ASTM F3299, DIN 53122-2, GB/T 21529, and YBB 00092003-2015 standards. It includes a standard configuration with optional accessories for container testing.
