Process analyzers are on-line tools for industrial process analytics. They are used to determine the chemical composition or physical properties of substances involved in industrial processes. They enable process optimization, asset protection, and compliance with environmental regulations.
With one of the most comprehensive families of sensors and on-line analyzers for pH, conductivity, dissolved oxygen, combustion oxygen, humidity, liquid and gas density and process gas chromatography, Yokogawa is recognized as a world leader in the field of analytical equipment. Accurate, repeatable measurement is the key to obtaining optimal results in your process, and Yokogawa's diagnostic-based analytical instrumentation offers the flexibility to meet a range of individual requirements. Whether for liquid or gas applications, our analyzers can resolve even the most demanding situations. Yokogawa's leadership in process analytics helps to protect the environment by reducing energy consumption and CO2 emissions.
To facilitate the accurate measurement of pH, and its presentation as a scale, a range of "standard liquids" or "buffer solutions" are used. These liquids, whose constituents are accurately defined, have known stable values. Although in the preceding text the relationship to hydrogen ions has been made, research has shown, that the activity of hydroxonium ions (H30+) is more relevant.
