Electrochemical Dissolved Oxygen Sensors. The original electrochemical (or amperometric) sensors were developed by Dr. Leland Clark in 1953 and the core technology has changed little since then. They have an anode and cathode surrounded by an electrolytic solution that is contained inside a plastic or glass body In order for water to support life, there must be oxygen dissolved into the liquid. This oxygen is not part of the water molecule, H 2 O, but is oxygen gas, O 2, dissolved in the water.There are a few ways to measure this dissolved oxygen content If the dissolved oxygen probe is outside of its normal working parameters, the instrument will give an out of range indication. Before performing maintenance cleaning of dissolved oxygen probes, always try fresh probe electrolyte solution and a new membrane
