BI's Model 4700E-series Electrodeless Conductivity Sensors are rugged, non-fouling, and have versatile mounting configurations, making them suitable for in-line or submersion mounting. A variety of wetted materials are available, including Polypropylene, PVDF and Hastelloy C.

Since these sensors have no electrodes, problems with contacting type electrodes - such as polarization, oily fouling, process coating, and contamination - will not affect their performance.

BI offers electrodeless sensors for solutions with conductivity as high as 2,000,000 microSiemens/cm, and with a temperature between 0 and 200°C.
