Water vapor permeation analyzer Lyssy L80-5000



Modular systems for precision water vapor permeabilty testing of packaging film barriers.

The 7000 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. A set of validation films and a spare P2O5 sensor comes as standard with all of our water vapor permeation analyzers.
