Ammonia in gases

Quantitative detection of NH₃ gas in gas mixtures

The OnlineNH3 is used for a quantitative determination of the released NH₃ in buildings for livestock, digestion towers and biogas plants.

The OnlineNH3 enables an increase of efficiency of treatment methods through the quantitative measurement of the NH₃-value in front and after filter plants respectively through measuring the individual process steps of a biogas plant.

Maintenance and cleaning cycles can be accurately identified and optimized.

Applications

As basis for NH₃ adjusted regulations (e. g. monitoring of air quality in livestock buildings)
Environment analysis

Fields of applications:

Industrial sectors
Animal husbandry
Biogas plants

Advantages

Continuous NH₃ determination in gases (measurement duration < 5 min)
Robust method of analysis
Automatic sample dosing
Easy calibration steps
Selective electrochemical sensor with no cross-sensitivity
Software easy-to-use
Output value of NH₃ as a 4 - 20 mA signal for integration into the local control system
Long lifetime of the sensors due to the intermittent gas switching
Integrated rinsing steps for measuring of continually fresh samples
Active sample intake of the gas up to a distance of 100 m – variable setup of device (wall mounted)
Also available for determination of hydrogen sulphide (H₂S), sulphur dioxide (SO₂) or ozone (O₃)
