Measuring Device for Determining NH3

Measuring Device for Determining NH3

In a device (1) for determining the NH3 content of a gas that is being measured, a first electrochemical gas sensor (2) and a second electrochemical gas sensors (3), which are set up for detection of the content of NO and/or NO2 and/or NOx in the gas that is being measured are provided, where the ga...

Beschreibung
Zusammenfassung:In a device (1) for determining the NH3 content of a gas that is being measured, a first electrochemical gas sensor (2) and a second electrochemical gas sensors (3), which are set up for detection of the content of NO and/or NO2 and/or NOx in the gas that is being measured are provided, where the gas being measured flows through the device and a converter (9) for catalytic conversion of NH3 to NOx is arranged in front of the second electrochemical gas sensor (3) in the direction of flow of the measured gas stream (4), while the first electrochemical gas sensor (2) is brought into contact with the unaltered gas (FIG. 1).
