    - O2 control in the aeration basin
    - Process water treatment and monitoring

  • Water works:
    - Status monitoring of drinking water (oxygen enrichment, corrosion protection, etc.)
    - Water quality monitoring in rivers, lakes or seas

  • Utilities of all industries:
    - O2 control in the biological treatment
    - Process water treatment and monitoring

The sensor is suitable for hazardous area use (ATEX, FM, CSA).

Benefits

  • Maximum measurement accuracy

  • Logging of sensor load data for easy traceability

  • Intelligent, self-monitoring sensor

  • Minimum calibration effort thanks to simple air calibration

  • Long maintenance intervals

  • Approved for hazardous area use

Videos

  • The concentration of oxygen dissolved in a liquid can be measured using the amperometric or optical measuring principles. This video shows what it is about and how these measuring principles work.

  • 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.
