Measurement of conductivity in high concentration areas.

The 4-electrode conductivity sensor TetraCon 700IQ is particularly suitable for a wide range of applications in high concentration areas compared to 2-electrode sensors, such as in treatment plants handling heavily loaded wastewater and effluent. It employs a unique measurement technology that reduces the effects of polarization, achieving high-precision measurements. The 4-electrode TetraCon 700 uses two pairs of independent electrodes, with the voltage electrodes generating a stable and consistent reference potential. The advantage of this technology is the reduction of measurement errors caused by polarization effects in high concentration areas. *There are also sensors available for seawater.
