The term “dissolved oxygen sensor” refers to the entire sensor assembly, including the electrodes, electrolyte solutions, membranes, and thermistor thermometers.
No external voltage is required. The difference in potential between the cathode and anode is greater than 0.5 volts. Galvanic probes are more stable and more accurate at low dissolved oxygen levels than polarographic probes. Galvanic probes often operate several months without electrolyte or membrane replacement, resulting in lower maintenance cost.

User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
Minimum flow rate of the aqueous solution through the sensor. In all DO probes, the membrane/sample interface should have a few cm/sec flow of the sample for precision performance. Without flow at the interface, the surrounding oxygen will be consumed and the local reading drops.
