FAQ

How does the Gas Analyzer 210 contribute to improving our plant efficiency?

With the Gas Analyzer 210, you can ensure the quality of your biomethane - and thus your yield. The precise and continuous measurement of methane (CH₄) and optional CO₂ allows you to keep control of your methanation processes at all times.

Thanks to continuous monitoring, you can detect fluctuations immediately and take targeted action. This allows you to get more methane out of your process - and achieve more profit per cubic meter of biomethane. The optimized gas quality increases the efficiency of your system.

What cost savings can we expect with this device?

Thanks to the long-term stable and drift-free technology of the Gas Analyzer 210, there is no need for frequent recalibrations or time-consuming maintenance work. As no test gas is required, you also save on operating costs and avoid handling gas cylinders.

This not only reduces your maintenance costs, but also minimizes operational interruptions and lowers the total cost of ownership in the long term. Reliable CH₄ and CO₂ measurement also contributes to stable process control and reduces system wear.

How precisely does the device measure CO₂ and CH₄?

The gas analyzer uses an NDIR single-beam method with a heated cuvette (60°C), which offers a high measurement accuracy of <1 % of the measured value in the range of 0.1-100 % by volume for CH₄ and optionally CO₂. With a detection limit of 0.1 % by volume, the analyzer delivers reliable results even at low concentrations.

How easy is it to integrate the Analyzer into our existing system?

Thanks to interfaces such as RS232, Profibus, Modbus and Profinet, the Analyzer can be flexibly integrated into different process control systems. This makes installation easier and commissioning goes smoothly.

What advantages does the Analyzer offer for the operational safety of our system?

Thanks to the real-time monitoring of methane and CO₂ concentrations and the fast measurement interval of just 20 seconds, the analyzer offers reliable control over critical process values. This enables early detection of fluctuations and protects your system from potential risks.

How user-friendly is the device in daily monitoring?

The intuitive touch display with simple menu navigation allows you to conveniently set and operate the device. The automatic zero point correction works entirely without test gases or the use of gas cylinders, thus reducing effort and potential sources of error.

All relevant CH₄ and CO₂ values and status messages are displayed clearly and concisely in real time. This allows you to recognize maintenance requirements at an early stage and keep an overview of your system at all times.

Thanks to integrated interfaces, the measured values can be easily transferred to your existing operating systems - for smooth integration into your processes.
