Wide Range Oxygen Probes for Gaseous & Dissolved O2 Monitoring

OXYBase® Series

The OXYBase® Series probes have a measurement range of 0 - 100 % O2 and can directly be connected to a control unit. The probes are waterproof and can be submerged completely, which makes them ideally suited for e. g. environmental research applications, aquaculture, and measurement in sewage. The probes' optical sensor is integrated in a removable sensor cap and can easily be exchanges. These caps are available in different versions to meet certain demands (e. g. fast response time, reduced bubble formation during dissolved O2 measurements, etc.). OXYBase® use either RS232 or RS485 as digital interface, and furthermore versions with one analog 4 - 20 mA output or two  4 - 20 mA current source outputs for O2 and temperature are available. Pick one of the OXYBase® probes below and learn more!

  • Ideal for environmental research, aquaculture, sewage, etc.
  • Waterproof
  • Communication via RS232 or RS485 (PreSens proprietary, Modbus RTU)
