Corrosion Products Sampler Quantify and Identify Corrosion Products  New electronic totalizer allows reset to zero The Sentry Corrosion Products Sampler (CPS) is a discrete module which can be mounted in a central sample panel or as a stand-alone unit at the sample source.  Easy-to-use filter holder  Measure effectiveness of chemical treatment  Identify sludge traps where corrosion products accumulate  Bypass capability allows isokinetic sample flow rates Background The control and prevention of corrosion are primary concerns of water chemists in the power plant. Left uncontrolled, corrosion can result in serious equipment failures. Of equal importance, deposition of corrosion products in the turbine or boiler can significantly reduce both capacity and efficiency of the plant. Since corrosion is a dynamic process, it is difficult to get a representative sample by normal grab sample methods. An integrating sampler is required. This means using filters to collect a continuous sample over a period of time, and measuring the amount of corrosion products which are captured by the filters. Major components include: 1. An easy-to-use, high pressure filter holder capable of containing a particulate filter, plus a combination of cation and anion filters. 2. A digital totalizing meter which is designed for high accuracy at very low flow rates. 3. Unit can either run on AC power or remotely with an optional 3-month-capacity battery. When the unit is plugged into AC, the battery is charged. The standard CPS is designed for portability so that it can be easily moved around the plant to conduct studies of corrosion product generation and transport within the system. A particulate filter is used to collect undissolved matter, and dissolved species are often collected via special cation and anion filters. Corrosion productS sampler
