The new flue gas analyzer testo 330 LL visualizes measurement data graphically

Independently of the technology used, every combustion system must function optimally. More than ever, requirement-based heat provision, low energy consumption and reduced pollutant emission are of central significance. In order to be able to exploit existing optimization potential as well as possible, regular testing and adjustment of the heating system is necessary. The new Testo flue gas analyzers testo 330-1 LL and testo 330-2 LL offer even more professional support in this thanks to new instrument functions. 

The new colour graphic display of the flue gas analyzer testo 330 LL visualizes the measurement data graphically: Self-explanatory graphic curves as well as easy symbols and clear colour design ease the analysis of the measurement data considerably.



The flue gas matrix

The central element of the new graphic processing of the measurement data is the flue gas matrix.
In the course of the flue gas measurement, this shows whether the CO and O2 values, as well as other measurement parameters, are in the green, permitted range, and the heating system is thus optimally adjusted.
Thumb symbols instantly show the status of the system. If the CO and O2 concentrations measured are in the green range, the thumbs point up.

Testo 330 User Interface

If the recorded measurement values are not within the optimum range, the symbols of the flue gas matrix provide important information for the required adjustment of the heating system.
Bad combustion – the CO concentration is over the defined limit value, the recorded CO content is not within the ideal range
Measurement value is not acceptable – the CO and O2 concentrations are considerably too high, the measurement values do not correspond to the prescribed norms and limit values
High loss – the O2 concentration is over the defined limit value, the heating system is not working efficiently.
