DO stands for Dissolved Oxygen, it is the measure of amount of gaseous oxygen dissolved in a solution. In theory, the amount of DO in a solution is dependent on 3 factors, namely temperature, salinity and atmospheric pressure. The measurement of DO requires a special DO electrode that is made up of an anode, a cathode, electrolyte solution and a gas permeable membrane.

Aquaculture: Use to monitor oxygen levels in catfish and shrimp farming; game stocking ponds; ornamental fish tanks and ponds; and in other fish farming applications.
Industrial: Ideal for checks the quality of plant water intake and discharge, wastewater and water treatment, recirculating systems and industrial process systems.
Environmental: Use to test water quality, monitor health of aquatic ecosystems, survey surface and ground water drinking supplies.
Educational: Ideal for quick, accurate DO readings in laboratories and schools.
