    Abstract - (Show below) - (Hide below)

    Applies to analyzers using membrane covered amperometric sensors for the continuous determination of dissolved oxygen partial pressure or concentration. Applies to analyzers for use on potable water, industrial process streams, industrial waste water, municipal waste water, and receiving bodies of water (e.g. lakes, rivers and estuaries).
