Based on the infrared moisture sensor principle, it provides high-precision and high-efficiency water vapor transmission rate (WVTR) testing for high and medium barrier materials. It is suitable for WVTR testing of film materials such as plastic films, paper-plastic composite films, co-extruded films, aluminized films, aluminum foil composite films, and glass fiber aluminum foil paper composite films, as well as sheet materials like PP, PVC, PVDC, metal foils, rubber, and silicon wafers in the fields of food, pharmaceuticals, medical devices, daily chemicals, photovoltaics, electronics, etc.
Based on the principle of the infrared moisture sensor. The pre-conditioned specimen is clamped between the test chambers. Nitrogen with stable relative humidity flows on one side of the film, while dry nitrogen flows on the other side. Due to the humidity gradient, water vapor diffuses from the high-humidity side through the film to the low-humidity side. On the low-humidity side, the permeated water vapor is carried by the flowing dry nitrogen to the infrared moisture sensor. Different concentrations of water vapor generate distinct optical signals, which are analyzed to determine current values and subsequently calculate the water vapor transmission rate (WVTR) of the specimen.
- Equipped with an imported infrared moisture sensor for a lower detection limit. Designed in accordance with the ASTM F1249 standard, it offers an ultra-long, non-consumable service life. Features over-limit alarms and automatic protection.
- Accurate Data: Utilizes 360° airflow circulation constant temperature technology for superior thermal stability. Equipped with high-precision temperature and humidity sensors for real-time monitoring and recording. Automatic control of flow rate, temperature, and relative humidity during the test ensures higher precision and test repeatability of 0.005g/(m2·24h) .
- Intelligent Control: Operated via a 10.1-inch touchscreen for enhanced convenience. In automatic mode, simply input the test temperature and humidity to start fully automated testing with one click. The new test chamber features pneumatic clamping for easy specimen replacement.
- Safe and Reliable: Operational Safety—Embedded with a proprietary high-end electronic system to eliminate system failures caused by computer viruses, ensuring reliable operation and data storage security. Operational Security—Equipped with various smart sensors (including optical) and audible/visual alarms to ensure safe operation. Performance Reliability—The instrument utilizes components from world-renowned brands for long-term stability.
- Powerful Functions: Professional test modes offer flexible and comprehensive control functions to meet research needs. Provides real-time curves for WVTR, temperature, and humidity. Ultra-wide test range and temperature range are available (customizable) to meet the barrier testing requirements of various materials under different conditions.
