Magnos28 Paramagnetic oxygen measurement reaches new heights

The Magnos28 represents the future of paramagnetic oxygen measurement, leveraging ABB’s pioneering technology leadership and over 75 years of innovation in the field of continuous gas analysis. This exciting new product completely rethinks paramagnetic oxygen analysis, replacing the glass dumbbell with a revolutionary new silicon sensor, the microwing.

Introducing the latest production techniques greatly improves repeatability and precision of the measurement. The automatic manufacturing process is capable of sub-micrometer precision leading to levels of quality and reproducibility beyond anything that is currently available on the market.

The ability to set individual measuring ranges allows the analyzer to be easily tailored to specific measurement requirements. An outstanding characteristic of this analyzer is its long term stability. In most applications, calibration of the zero-point with ambient air or nitrogen is only required once a month. It is also suitable for measuring rapid changes in the concentration of the sample gas.



LS25 is in-situ cross duct analyzers for measuring gas concentrations. It apply the highly selective, optical measuring principle of tunable diode laser (TDL) absorption spectroscopy.  For measurement purposes a single absorption line is selected from the gas to be measured in the near infrared spectral range, at which no cross-sensitivity from other gases occurs. The absorption line is scanned and the receiver located opposite detects the absorption caused by the sample gas and calculates the gas concentration from this. The transmission rate is displayed as a signal for predictive maintenance.


MultiFID14 FIDAS 24

In its most extensive version, an Advance Optima multi-analyzer system consists of four analyzer modules and it can measure six different components. Communication takes lace via its internal system bus. Other locally installed system components for the conditioning of sample gas, such as sample gas feeding units and coolers, can also be integrated. All the modules are operated by the central processing unit – and the analyzer module can even be installed up to 350 m away.
