Optical Dissolved Oxygen Sensor - The Optical O2-Sensor


First optical oxygen sensor with SCS interface! (Simulation Clark-Sensor) Perfect integration into running systems. The ideal substitute for your existing oxygen sensors.


    Your advantages

  • singular calibration
  • minimal operating costs
  • suitable for fresh and salt water (no oxidating parts)
  • quick reaction time
  • no inflow necessary
  • robust and easily exchangeable sensor cap
  • auto malfunction diagnosis
  • no additional transmitters needed
  • best price-performance ratio
ODOS oxygen sensor submersible version


    Application areas

  • aquaculture
  • lake und river monitoring
  • fish farming (fresh and seawater)
  • water treatment (control of the O2-loading in activated-sludge tank)
  • service and industrial water
  • research (can be connected directly to a PC via an optional USB converter, no further devices needed)


    Four connection options

  • 4 - 20mA current output
  • RS485 Modbus RTU-interface
  • SCS Simulation Clark-Sensor (galvanic isolation)
  • iks AquaStar Industrial


    Most easy maintenance

    • robust and easily exchangeable sensor cap
    • pre-calibrated, at once from factory usable sensors minimize maintenance time as well as costs


By the integrated 4-20mA current interface in 2-wire technology or the digital Modbus RTU-interface ODOS can be connected directly with an SPS or a process control system.
By the integrated SCS interface ODOS is downward compatible towards classical sensors with electrolyte solution. Thus existing plants can be equipped by most modern optical measurement technology without any problems.

Model range

Especially for fish farming and aquaculture we have developed a particularly robust submersible version (s. front page) including a biting protection. This version can be used up to a water depth of 50m. Furthermore the sensor can be delivered with an IP68 connector plug or with fixed cable in different lengths.
For mounting into a probe holder the sensor can be delivered optionally with a 1” process connector.
With our mounting set (order-no. 1682) the sensor (models 5000, 5001 and 5002) can be mounted into the ODOS probe holder.
