Memosens 2.0 glass electrode for application in drinking water and swimming pools

Drinking water

Swimming pool water

pH compensation for free chlorine and free bromine measurement

Reliable: Ceramic junction ensures reliable measurement at low conductivities. For minimum conductivities, 3 junctions are the best choice.

Robust: The optional salt storage provides for extended operating time.

Precise: The sensor shows minimum drift thanks to a very low level of ion depletion in electrolyte.

Memosens 2.0 offers extended storage of calibration and process data. These data are the ideal basis for predictive maintenance and can also be used to develop and provide enhanced IIoT services.

Safe: Non-contact, inductive, digital signal transmission eliminates errors due to moisture.

Cost-efficient: Fast sensor exchange in the field increases process uptime and regeneration extends the sensor lifetime.

The pH-value of a liquid can be calculated using the potentiometric measurement principle. This video shows what it is about and how this measuring principle works.

Memosens converts the measured value to a digital signal and transfers it to the transmitter without a contacting connection. This video shows how Memosens optimizes process control and maintenance.
