SIRA – UV-Analyzer

The SIRA process gas analyzer is the standard device for the prescribed determination of the odorant concentration in accordance with DVGW worksheet G 280 and G24. The analyzer is also able to determine the concentration of aromatic hydrocarbons. 

The measurement is carried out using UV spectrometry. Adapted analysis systems including internal zero gas generation are available for the respective odorant. The analysis system can be adjusted at any time when the odorant is changed.​

The analyzer is suitable for operation in natural gas and hydrogen. The measurement of aromatic hydrocarbons in nitrogen is also possible. ​

Measurements with different gases can be carried out time-controlled through optimal switching of the measuring points.

The SIRA product platform includes various sensor technologies that can be used both independently and in combination with one another. The modular platform concept creates a flexibly configurable device system for analyzing various parameters.
