Four-electrode sensor made of stainless steel with a wide measuring range and Memosens technology for laboratory and random sample measurement in the field. Ideal for measurements where a broad conductivity measurement range in one system is needed. Memosens technology is based on true Plug & Play for minimised downtime. Measured values, calibration data, and history are stored directly in the sensor. Memosens offers absolutely secure data transmission and thus ensures increased availability of the measuring point and trouble-free processes. In addition, the inductive Memosens coupling is insensitive to moisture and corrosion.
