Product description
The OnlineNH3 system enables continuous and precise quantitative determination of ammonia (NH3) in gas mixtures.
Designed with an integrated dilution step, the system can handle a wide measurement range – from very high concentrations (100 to 20,000 ppm) to very low levels down to the odour threshold (0.1 to 100 ppm).
Reliable Technology for Demanding Applications
The OnlineNH3 features a selective amperometric sensor with gas-selective membranes, membrane pumps for sample transport, and an integrated PC for real-time data recording, trend analysis, and alarm management.
Measurement values can be transmitted directly to the control room via analog and digital (alarm) outputs.
An integrated cleaning system ensures drift-free analysis even in oxygen-free gases such as biogas, significantly extending the sensor lifetime through stress-free operation.
Thanks to its precise and stable measurement principle, the OnlineNH3 is ideal for ammonia-controlled regulation of enrichment and purification processes.
Flexible System Design
The same technology platform is also available for continuous monitoring of hydrogen sulphide (H2S), sulfur dioxide (SO3), or ozone (O3).
Applications
- As basis for NH3 adjusted regulations (e. g. monitoring of air quality in livestock buildings)
- Environment analysis
- Industrial sectors
- Animal husbandry
- Biogas plants
Advantages
- Fully automated sample dosing
- Hardly any cross-sensitivities due to selective electrochemical sensor
- Output 4 to 20 mA for integration of the NH3 signal into the local control system
- Long sensor life due to intermittent gas path gas path switching
- Active sample aspiration, thus free installation (wall mounting) with up to 100 m distance from the sampling point
Features and Results
- Continuous NH3 determination in gases (measurement duration under 5 min)
- Robust analysis method
- Easy calibration steps
- Software easy-to-use
- 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)
