Hydro-Air - Dissolved Oxygen Sensor (Polarographic)

Hydro Air DO sensor is membrane based and uses polarographic technology to determine dissolved oxygen levels. The sensor is comprised of double-electrode cell, with a cathode and an anode, joined by the electrolyte and separated from the sample by a permeable membrane. The sensor generates a potential, mV, related to the dissolved oxygen in contact with membrane. It provides low cost solution for the dissolved oxygen measurement typically in the aeration tank and in the aquaculture ponds.
