  • Long-term stability due to the optical measurement principle
  • Range 0 - 20 mg O2 per l / 0 - 200% saturation
  • Minimum of maintenance
  • Ideal aquaculture applications
  • Precise
  • Nearly maintenance free
  • Independend from flow
  • Inclusive integrated temperature sensor
  • Robust stainless steel housing

Due to the optical measurement principle, the sensor does not need to be refilled with consumeables and has no expendable parts except the sensor cap, which can be easily replaced after years of operation. The minimum lifetime of the cap is 1.000.000 measurements. 

This makes the SENECT Oxygen Sensor O2S perfectly suitable for many applications, especially for the regulation of the oxygen concentration e.g. in aquaculture farms.
