The E+H Memosens CLS21E is a digital 2-electrode conductivity sensor for consistent monitoring of medium conductivity applications including potable water, wastewater, industrial water treatment, desalination, and river/lake monitoring. Its rugged PES shaft and graphite electrodes provide corrosion resistance and high mechanical stability for extended service life.

The sensor operates with cell constant k=1 covering 10 µS/cm to 20 mS/cm. Process temperature range -20 to 135°C at 3.5 bar, pressure 17 bar at 20°C. Integrated Pt1000 temperature sensor ensures accurate compensation. Memosens 2.0 technology enables non-contact inductive signal transmission, extended storage of calibration data, and predictive maintenance via IIoT. IP68 rated. ATEX, IECEx, CSA, NEPSI, and marine approvals (ABS, LR, BV, DNV) available.
