Your benefits

  • Three application-optimised sensor ranges available
  • Precise, real-time amperometric measurement for efficient process control (short response time)
  • Amperometric measuring eliminates interference caused by turbidity or colouration
  • Integrated or rapid external temperature compensation eliminates interference caused by influence of temperature
  • Diaphragm-covered sensors for reduced dependence on flow, cross-sensitivities, substances in water and film-forming media
  • Diaphragm-covered measuring electrodes embedded in an electrolyte ensure long service life. This maintains optimum measuring conditions regardless of process conditions

Field of application

Product range CDE: potable, industrial and process water without surfactants with slow temperature changes Product range CDP: bottle-washing systems and other applications with addition of surfactants and rapid temperature changes Product range CDR: polluted industrial / process water, water containing surfactants, cooling water, irrigation water, waste water with little pollution, hot water
