Unmatched Performance in a Water Vapour Transmission WVTR Analyser !

The Model 7001 Water Vapour Transmission Rate WVTR Analyser uses a well proven sensor technology to measure water vapour transmission rate (WVTR) lower than other instruments on the market.  With a measurement range of 0.0002 to 64.5 g/100in2/day, the Model 7001 Water Vapour Transmission Rate WVTR Analyser is ideally suited for food packaging films, pharmaceutical packaging, and electronics packaging.

Water vapour transmission rate (WVTR) is the measure of how much moisture passes through packaging material.  WVTR is an important property of packaging material especially in food packaging.  Breads and cookies need to be protected from moisture using high barrier WVTR materials.  Other applications where WVTR is important is in building materials such as house wrap.  It is important to keep a house free from outside moisture.  Therefore manufacturers of house wrap need to know the WVTR of their material.

Illinois Instruments also offers oxygen permeation analysers, and headspace analysers as well as permeation testing service.  Use the menu above to contact us to have your films tested for water vapour transmission rate (WVTR) or oxygen permeation rate (OTR).

Illinois Instruments’ Model 7001 Water Vapour Permeation Analyser, WVTR Analyser, represents the ultimate in performance and simplicity of operation.

Precision balanced electronics and gas handling subsystems ensure only the highest levels of performance and repeatability available.

Computer controlled temperature and humidity simulate actual or investigative climatic conditions making the 7001WVTR Analyser ideal for testing and researching both current and newly formulated packaging film materials.

Calibration can utilize both NIST traceable gases and films for versatility of film to film comparison and reliability of analysis data.

Standard Windows® based software and complete control of test parameters make the Model 7001 the most precise, flexible, and easy to operate water vapour permeation analyser of its kind.
