The contacting conductivity sensor performs reliably and accurately even in hazardous areas. CLS15E features Memosens 2.0 digital technology, offering extended storage of calibration, adjustment and process data. It facilitates predictive maintenance and provides the perfect basis for IIoT services.

Memosens CLS15E measures conductivity in pure and ultrapure water applications for the monitoring and control of:

• Boiler feedwater

• Ion exchangers

• Reverse osmosis

• Cooling water

• Distillation

• Chip cleaning

The digital sensor can be used in power plants for:

• Degassed conductivity

• pH measurement with differential conductivity

With its international explosion protection approvals, such as ATEX and FM, the sensor is suitable for hazardous area use.
