Optical Dissolved Oxygen Sensor

The RDO Pro Optical DO Sensor can be connected directly to a PLC for seamless integration with any industrial control system.

An optional AV38 local display / controller is available to provide a versatile system for more conventional installations. This option offers single or dual sensor inputs. It provides an ideal solution for monitoring all dissolved oxygen levels throughout a wastewater treatment plant.

The RDO Pro covers a measurement range of 0 ? 20 ppm and features a plug and play design with digital interface. No membranes are required for the sensor, just a simple, once a year cap replacement. ?

There is no cross sensitivity to carbon dioxide, sulphide, sulphate, ammonia, chloride or hydrogen sulphide.

Typical applications include:

  • Aquaculture
  • Wastewater
  • Chemical process
  • Fermentation
  • Food and dairy
  • Bio-processing
  • Other industrial processes
