Measure the level of dissolved hydrogen sulfide directly in wastewater.

Oil & Gas

Get real-time measurements of all H2S levels with no delay.


Precisely identify peaks in H2S levels in the biogas production process.

What is a SulfiLoggerTM sensor?

The SulfiLoggerTM sensor is a robust microelectrochemical sensor capable of providing highly accurate, continuous hydrogen sulfide measurements under extreme conditions in wastewater sewer networks and gas pipelines.

Measuring directly in wastewater or unprocessed natural gas and biogas, the SulfiLoggerTM sensor works where other sensors give up. The sensor is easy to install. It has no buttons, is always on and will continue to deliver H2S readings in real-time when connected to a power source.

Reveal new information about your H2S challenges

The groundbreaking SulfiLoggerTM sensor measures the levels of H2S directly in wastewater, oil & gas, and biogas applications. With the SulfiLoggerTM sensor you can access the black box of information from your pipelines or sewage networks, that you were unable to access before.

The SulfiLoggerTM sensor provides you with:

“With the real time aqueous H2S data, we are hopeful that our chemical feed systems will be optimized to control H2S to a very low concentration while providing chemical cost savings, digester gas scrubber media savings, and corrosion prevention.”
