Systech AquaSense 7101 Water Vapor Permeation

Brought to you by Systech, our specialist brand for moisture, gas, and oxygen analysis, the AquaSense™ 7101 water vapor transmission rate (WVTR) analyzer delivers absolute moisture measurement with precision temperature and humidity control.

Designed for accurate measurement of moisture vapor transmission through packaging films and materials, it is ideal for quality control, R&D, and barrier performance testing of both existing and newly developed packaging structures.

High-precision WVTR testing

The proprietary phosphorus pentoxide (P₂O₅) coulometric sensor forms the core of the AquaSense™ 7101. Consisting of dual platinum windings around a quartz tube, the sensor operates according to Faraday’s Law, providing an intrinsic and absolute measurement of moisture.

Because the measurement principle is absolute, the sensor does not require routine calibration, reducing maintenance time while maintaining high accuracy.

Wide WVTR measurement range

The high-sensitivity P₂O₅ coulometric sensor provides stable, precise water vapor transmission  rate measurement across a wide range of 0.002–1000 g/m²/day, enabling accurate testing from ultra-low transmission rates for high-barrier materials through to higher permeation levels across a broad range of packaging applications.

ASTM and ISO compliant testing

The AquaSense™ 7101 is compliant with international standards written specifically for coulometric WVTR measurement, including ASTM F3299-18 and ISO 15106-3. This ensures reliable, traceable results aligned with globally recognized test methods.

WVTR testing – made easy

Operation is simple: load the sample, set the required conditions, and start the test. The trademarked Q-Seal™ gas-free cell closure system simplifies film loading while helping reduce testing time and operational costs.

Touchscreen operation

The large touchscreen interface provides intuitive operation. Users can easily define test conditions such as temperature and relative humidity, supporting efficient setup and repeatable testing procedures.

Multi-condition WVTR testing  

Using the trademarked Test Condition Matrix (TCM™) functionality, the AquaSense™ 7101 can automatically test a sample at up to ten different temperature and humidity conditions in sequence, improving productivity and reducing operator intervention.

Expandable WVTR testing capability

The system is designed for productivity and scalability, with expandable satellite capability allowing multiple test cells to be added as testing requirements grow. This enables increased throughput while minimizing additional instrument costs.

Reliable, low-cost sensor operation

The long-life coulometric sensor is protected by Anti-Surge™ technology, which prevents damage from excessive moisture exposure and helps extend sensor life while maintaining measurement stability.

Networking and connectivity

The analyzer operates on a full Windows® operating system, enabling secure operation, data management, and network connectivity within laboratory environments.

Remote WVTR testing support 

With user permission, remote access support allows fast diagnosis and resolution of system issues without the need for on-site visits, minimizing downtime and service costs.
