Explosion hazard in the sludge hall: When sensors go “blind.”
Hydrogen sulfide and moisture often turn conventional methane monitoring into a safety risk. Learn why the right measurement principle determines whether you get a false alarm or real safety – and how to cleverly position the technology outside the Ex zone.

Phosphine Measurement in the Food Industry with NDIR: Precise PH3 Monitoring for Safe Fumigation
Phosphine Measurement without Compromise: Safe. Selective. Low Maintenance. In the food industry, every detail counts in fumigation. Our NDIR analyzers precisely monitor phosphine concentrations from the high fumigation range to critical release measurement (OEL). Rely on the durable measurement technology from Fresenius Umwelttechnik – for maximum process reliability without constant sensor replacement.
Trace-gas H2S measurement in multi-stage biogas cleaning | NDUV
Continuous monitoring of hydrogen sulfide is essential for upgrading biogas to biomethane, but due to drastically varying concentrations and extreme process conditions—such as 300°C, 10 bar pressure, and high hydrogen content—it places the highest demands on analytics. This is where classic electrochemical sensors reach their limits, making the NDUV technology of the GA210 analyzers from Fresenius Umwelttechnik an efficient solution.
HCl Measurement in Ambient Air: Electrochemical Trace Gas Analysis
The GA210 from Fresenius Umwelttechnik enables highly precise monitoring of hydrogen chloride immissions in ambient air. By utilizing sensitive electrochemical sensor technology, the compact system reliably detects even the smallest trace concentrations from 0.5 ppm. Automatic calibration functions and a robust design make the analyzer a low-maintenance, long-term stable solution that can be both permanently installed and flexibly used as a rental unit.
CO Measurement up to the Explosion Limit in RTO Systems | LEL
CO Monitoring in RTO Systems: Safe. Fast. Reliable.
At the lower explosion limit, there is no margin for error. The SC300 LEL analyzer combines robust NDIR measurement technology with a response time of only 5 seconds. This provides the chemical industry with a highly specialized solution for CO measurement in potentially explosive atmospheres—including intelligent sample conditioning.
