Your benefits

  • Two application-optimised sensor types available
  • Precise, real-time amperometric measurement for efficient process control (short response time)
  • Amperometric measuring eliminates interference caused by turbidity or colouration
  • Integrated temperature compensation eliminates interference caused by influence of temperature
  • Diaphragm-covered electrodes 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
