NDUV sensor technology now ready for corrosive gases

In many areas of process engineering, reactive gases are used as starting products in chemical processes. These gases often are corrosive, so that only certain materials can be used. In process measurement technology, these gases are usually detected with special photometers that are located locally outside the process. The process gas therefore comes in contact with all materials on its way from the process to the sample cell. Both the design of the gas paths and that of the sample cell must therefore be adapted to these requirements.
