The Odor Online analyzer from Axel Semrau sets the standard for accurate, real-time detection of sulfur compounds in natural gas pipelines. Whether tracking odorant levels, H₂S, or total sulfur content, this analyzer delivers lab-quality results with field-ready reliability. Preloaded with custom calibration gas and backed by PERC’s expert installation and training, it’s a turnkey solution built for performance and peace of mind.

WHY ODOR ONLINE
In many gas systems a continuous, automatic measurement of the concentration of odorants is the safest, simplest method of maintaining a consistent level throughout your network. In many cases, i,e, where the gas has already been odorized by the previous supplier, the automatic measuring technology ensures the greatest safety by enabling remote transmission of odorant levels and/or alarms at pre-configured levels. Construction of the Odor On-Line as a fully automated system ensures low operating costs and the absolute minimum amount of required periodic maintenance.

CONTROL AND DATA COLLECTION
Odor control software is characterized by its simple operation and clear navigation. The current chromatogram and the last measured value are always displayed on the main screen. All measurements taken are archived and can be evaluated again at any time. Individual reports can be compiled. Measurements can be exported via CSV files to other programs, such as Microsoft Excel. Remote servicing is likewise possible in conjunction with supplementary programs and a modem connection.
Sample results below from Odor Online offers smooth, well defined, repeatable peaks for analysis and comparison.
