Sensor Oxygen O2S


  • 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

Minimal maintenance - reliable oxygen measurements.

The SENECT Oxygen Sensor O2S measures the concentration of dissolved oxygen in water reliable with a minimum of maintenance. Based on the principle of optical luminescence quenching, the sensor inspires with accurate and long-term stable measurements and does not depend on flow.

  • 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.
