This galvanic dissolved oxygen probe consists of a silicone membrane, an anode bathed in an electrolyte and a cathode. Oxygen molecules defuse through the probes membrane at a constant rate (without the membrane the reaction happens to quickly). Once the oxygen molecules have crossed the membrane they are reduced at the cathode and a small voltage is produced. If no oxygen molecules are present, the probe will output 0 mV. As the oxygen increases so does the mV output from the probe. Each probe will output a different voltage in the presence of oxygen. The only thing that is constant is that 0mV = 0 Oxygen.


Because every use case is different, there is no set schedule for recalibration. The dissolved oxygen probe reacts with oxygen in the water, the more oxygen it reacts with the more the probe is depleted of its electrolyte solution. Typically an industrial dissolved oxygen probe will last 2 years before the electrolyte is depleted (results will vary). When the electrolyte is depleted, the probe will read very low numbers. Best practice is to replace the electrolyte solution and membrane every 1 – 2 years.
