AquaSense 7101 Water Vapor Permeation

Water Vapor Transmission Rate Analyser 7101 implying our latest, high-sensitivity coulometric sensor

Applications: Permeation Testing

SKU: MDL-007101 Category:


The 7101 water vapor analyzer range utilises the sensitive and stable P2O5 sensor for absolute moisture measurement. These water vapor analyzers offer a wide measurement range of 0.002-1000 g/m²/day and precision temperature, humidity and flow control. Providing accurate and repeatable results for research and development testing of water transmission rate (wvtr) in both current and newly formulated packaging film materials and fast testing for Quality Control.

All Systech Illinois analyzers are certified traceable to NIST. In addition, analytical performance is validated using NIST certified gases and NIST traceable films.

For this product we have a special DualPerm package available.
The DualPerm is a combination package offering substantial cost savings compared to the purchase of two separate permeation analysers. This OTR Analyser and WVTR package allows the sharing of one computer/tablet interface and results, saving time and space on the work bench. Utilising a shared nitrogen source it will save on running and cylinder rental costs. Also, installation costs are reduced by setting up the system all at the same time.

The DualPerm includes all of the features and benefits of our 8100 Oxygen Permeation and 7100 Water Vapour Permeation Analysers.
