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.

Hot-Wet Measurement: Gas Analysis without Washout Loss
Cooling leads to loss: For water-soluble gases like formaldehyde or ethanol, a conventional gas cooler simply washes away up to 35% of your measured values. Learn why physics is not a matter of choice and how Fresenius Umwelttechnik’s hot-wet solutions ensure precise results instead of systematic measurement errors.
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.
