Oil and Gas Industry
Water activity, or equilibrium relative humidity (ERH%), is widely used as a quality control measure in the Oil & Gas industry to formulate materials used for drilling and processing
Measuring water activity
Challenges in measuring water activity
Drilling materials often contain many ingredients that are solvent-based so protection of the water activity sensor cell is essential. A filter combination of alcohol and chemical layerswith a special formulated sensor cell CM3 is specified for this application.
