Description

When you’re working out in the field, you can rely on precise technology. However, precision technology is useless if it is not adaptable, versatile, and easy to utilise in the field. The testo 340 flue gas analyzer exceeds all of these requirements and more.
The testo 340 is used to measure industrial emissions.
What sensors do you require in your day-to-day work, and what measurements do you usually need to take? The testo 340 comes with an O2 sensor as standard, as well as four additional sensors (CO, COlow, NO, NOlow, NO2, or SO2) to choose from, allowing you to tailor your testo 340 to your specific needs.The analyzer’s small size and dependable technology allow for greater mobility, making it perfect for use in on-site service activities, such as installing or testing fire facilities or energy production systems. Simply click on the “Applications” page to learn more about the many application possibilities and to check which industrial applications your testo 340 flue gas analyzer is suitable for.

High gas concentrations? No problem with the flue gas analyzer testo 340!
The flue gas analyzer has a wide measuring range, allowing you to take measurements even at very high gas concentrations (i.e. during industrial flue gas analysis). When high gas concentrations arise suddenly, the extended measuring range (thinning) is immediately engaged. The sensor is put to the same test as when the flue gas analyzer is utilised at low gas concentrations.

Applications

Analysis of the gas atmosphere (thermal processes)

Flue gas analysis is used for thermal manufacturing processes, from ongoing emission control, via setting and optimisation of combustion systems, through to process monitoring. Flue gas analysis instruments serve to optimise operations and save fuel. At the same time, flue gas measurement enables checking and monitoring of flue gas emission limit values laid down by the authorities, along with functional testing of permanently installed emission instruments. Flue gas analysis instruments are increasingly used for monitoring process and product quality.
Advantages of the testo 340
Ideal for measurements at high concentrations

When recording extremely high concentrations, the measuring range extension is automatically activated. This enables continuation of the measurement. The gas sensor is not subjected to any higher stress than it is at low gas concentrations. This ensures the sensor has the longest possible service life.

Service measurement on industrial engines

Flue gas analysis instruments are one of the items of equipment that are used on a daily basis by service engineers to achieve optimum tuning of engines. Flue gas measurement is used on industrial engines when they are commissioned, at regular maintenance intervals or for troubleshooting when they are running in an unstable way. The background to flue gas measurement is tuning the engine to the optimum operating parameters while complying with the limit value regulations in force. Maintenance work that is carried out regularly makes an important contribution to avoiding downtimes over the long term, to ensuring the quality of the system and thus a high level of efficiency and to having a significant influence on emission levels.
Advantages of the testo 340

Separate NO and NO2 measurement

The real NOx value is measured with the NO and NO2 sensor combination. In gas engines, the NO2 component of the NOx value can fluctuate greatly, so the separate measurement of each of the gases is necessary for correct NOx values.

Measurements even at high CO concentrations

At unexpectedly high concentrations (up to 50,000 ppm), the automatic dilution of the sensor with fresh air allows measurements even when the engine conditions are not defined, without negatively affecting the service life of the sensor.

Special flue gas probes for industrial engines as an accessory

These probes are highly heat-resistant and specially designed to compensate for different pressure conditions, e. g. for measurements before and after the catalytic converter.

Engine-specific parameters

The most important parameters for industrial engines such as O2, CO, NO, NO2, NOx and Lambda can be displayed simultaneously.

Service measurement on industrial burners

The testo 340 flue gas analysis instrument offers service engineers a vast range of technical functions. In addition to compliance with environmental regulations, it can also be used to check correct functioning and to optimise burner efficiency. Flue gas measurement is used on industrial burners for safe and efficient commissioning, at regular maintenance intervals or for troubleshooting when they are running in an unstable way.
Advantages of the testo 340

Time saving through helpful instrument pre-settings

Typical fuels, a sensible sequence of flue gas parameters in the display and useful instrument settings are preset for each application. Tips on the display take the user through the measurement (no prior knowledge specific to the instrument needed). The testo 340 is ready for operation within just a few minutes.

Unrestricted measuring at high concentrations

When commissioning burners or carrying out measurements on unfamiliar systems, very high concentrations can occur unexpectedly. The measuring range extension is automatically activated in such cases.

Always ready for use – even in tough day-to-day work

The robust housing protects the measuring instrument from knocks.
