The probe holds a lot of electrolyte so it will last for a long time before needing reconditioning. The built-in PT-1000 temp sensor and threaded body reduces the need for excess parts and makes it easy to install in a pipe.
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.
