The oxygen sensor uses luminescence-based optical measurement technology and measures reliably and precisely. The low maintenance and small amount of consumable materials needed by the sensor provide immediate returns on investment. Only the membrane cap must be replaced every two years. The sensor can also be used in applications with a very weak water flow. The oxygen sensor is available with a 10-meter or a 2-meter cable.

  • Low operation costs thanks to low maintenance (no electrolyte replacement)
  • Larger calibration interval thanks to low deviations
  • No polarisation voltage necessary
  • High degree of measurement accuracy, even at low concentrations
  • Fast response time
  • No minimum inflow (no oxygen consumption)
