Abstract
Method and apparatus for electrochemical monitoring of oxidizing agents, such as nitrite, or reducing agents in a water system and for controlling concentration levels for protecting surfaces exposed to the water. The apparatus includes a probe for selective exposure to fresh water samples of the system. The probe is connected to an analyzer that operates the probe and measures agent concentration by a chronoamperometry technique. A controller selectively feeds an agent to the water system in accordance with a set point to maintain a desired concentration level.
