Abstract
An oxygen analyzer which measures the level of dissolved oxygen in a liquid stream. The measuring process embodies chronoamperoemetry of pulsed potential voltammetry. The signal from the electrode is real time averaged. The analyzer does not require temperature, salinity or pressure compensation circuitry and does not have to be calibrated repeatedly.
