Fresenius Umwelttechnik GmbH provides state-of-the-art process measurement technology for industrial applications, helping operators maximize efficiency and comply with regulations through precise analytics.
Since 1992 we have been developing process measurement technology for gases in Herten, Germany. Our solutions include stationary and portable gas analyzers for biogas, wastewater treatment, recycling, chemicals, pharmaceuticals and emissions monitoring.
Industries
Our gas analyzers and process measurement technology help companies across many industries to run processes efficiently, protect their plants and reliably meet regulatory requirements.
Methane and CO₂ analysis for running biogas plants: the BioBasic measures CH₄ and H₂S, optionally CO₂, O₂ and H₂ – at up to five sampling points.
Continuous monitoring of process gases, solvents and oxygen – for example during inerting with paramagnetic O₂ measurement.
Gas analysis in the food and beverage industry: O₂ and CO₂ for protective gas, storage and fermentation processes.
Gas analysis for fermentation, drying and inerting – with readings you can document for your quality assurance.
Digester gas analysis and off-gas measurement (N₂O, CH₄, CO₂) for municipal and industrial wastewater treatment plants.
Landfill gas monitoring and process control for mechanical-biological treatment plants (MBT).
What to expect
Several gases in one device: up to six IR components in the GA 320, NDIR combined with electrochemical sensors and zirconia in the GA 220 – at up to eight sampling points.
View productsDeveloped in Herten, made in Germany. Readings and records that help you prove regulatory compliance and support your quality assurance.
Maintenance, calibration, spare parts and training – worldwide, including on site at the customer.
View serviceMeasuring principles
Which measuring principle fits depends on your gas, the measuring range and the rest of the sample gas. Our process measurement technology combines the principles – even in one device.
Non-dispersive infrared
CH₄, CO₂, N₂O, solvents, refrigerants
Every IR-active gas absorbs at its own wavelength – so the device measures gases selectively and with long-term stability.
Heated measuring cell, 85 °C
Formaldehyde in the exhaust of gas engines
The sample gas arrives uncooled through a heated hose. Water-soluble gases stay in the gas instead of being lost with the condensate.
Selective oxygen measurement
O₂
Oxygen is attracted by a magnetic field – unlike almost all other gases. The measurement needs no consumable sensor.
Heated ceramic
O₂ up to 100 vol.%
The ceramic conducts oxygen ions, the resulting voltage shows the O₂ content. Fast and compact.
EC sensors
O₂, H₂S, H₂
The gas reacts at an electrode, the current is proportional to the concentration – also as a complement to NDIR in the same device.
TCD
H₂
Hydrogen conducts heat much better than air. As a module in the GA 210 or GA 220, it measures H₂ even at high concentrations.
