Conductivity measurement is widely used in industrial and environmental applications as a simple and inexpensive way to monitor and to control the ionic concentration in a solution:
Chemical Processing
In bio or chemical processes, iST conductivity sensors are used to support the control of the chemical's concentration. In pharmaceuticals, measuring the ion concentration during the drug manufacturing processes maintains the quality and purity standards.
Fuel Cells
The monitoring of electrical conductivity of the coolant used in fuel cells and their real-time data helps ensure the coolant is free from contaminants that could affect the hydrogen fuel cell's performance and longevity. In proton exchange membrane (PEM) fuel cells, conductivity sensors monitor the ion exchange process and thereby maintaining the membrane's efficiency.
