How Do Dissolved Oxygen Probes Work?

Dissolved oxygen probes work by measuring the amount of oxygen that diffuses across a permeable (or semi-permeable) membrane into a probe (sensor). Once oxygen is inside the sensor, a chemical reduction reaction occurs, producing an electrical signal. This signal is read by the DO probe and is displayed on a meter.  Dissolved oxygen (DO) comes …
