Conductivity measurements are widely needed in industrial and environmental applications as a simple and inexpensive way to monitor and to control the ionic concentration in a solution. These sensors are vital for measuring conductivity in a wide array of applications, including water treatment (drinking water, wastewater, irrigation runoff), food and beverage processing (cleaning, product quality), chemical processing (product quality, process control), power generation (boiler feedwater purity), aquaculture, salinity studies, and estuary monitoring. With wetted parts made from non-metallic materials, these sensors can be employed to measure in difficult and often corrosive liquids such as seawater and sewerage. With a broad range of 10 µS/cm to 200 mS/cm, iSENSE provides conductivity sensors in different chip sizes and cell constants for specialized applications.
