Emission Analyser – Testo 340

The testo 340 Emission Analyzer is a single solution for a range of applications. From burner tuning, to optimizing combustion process in boilers and  furnaces,  from  diesel engine exhaust analysis, to NOx monitoring in gas turbines,  from  flue gas analysis in incinerators, to measuring emissions in gas engines, you name it and the 340 can handle it.

It’s a powerful instrument, yet surprisingly comes in a relatively smaller footprint. It is equipped with a maximum of 4 gas sensors, and one can select gases based on one’s needs, and applications. You can choose from O2, CO, NO, NO2, SO2, No low and CO low.

A wide range of modular probes can be fitted, with varying lengths of 335 to 700 mm. one can also use the heavy-duty industrial probe, where lengths of up to 3 meters are possible. These probes are made of different materials depending on the stack temperatures. Inconel is used for temperatures up to 1200 deg C, and Aluminium Oxide is used for temperatures up to 1800 deg C.

For sample extraction, a heavy-duty pump provides a constant flow within a stack gas pressure ranging from   -200 to +50 mbar. In case of gas concentration going over range, a built-in dilution will extend the range of all sensors by 5 times. A built-in condensate trap prevents moisture from entering the sensors, and the instrument warns if the condensate trap is full and needs to be emptied.

Parameters like efficiency, air ratio, flue gas loss are calculated and displayed. The analyser comes with a powerful internal diagnostic feature. One can know the sensor status, last calibration done, pump flow, battery level and life, serial no, instrument version etc, at the press of a button. A user friendly “easy emission” software helps with the analysis, and for generation of reports, in graphical and tabulated formats.

For NOx measurement either real NOx can be measured using 2 sensors for NO & NOx, or NO2 can be calculated from NO, and then NOx is derived. It has a comprehensive memory, where 200 logs can be stored per site, and 10 such sites per folder, while a total of 100 folders can be stored.

Up to a maximum of 10 user defined fuels, including test gas as a fuel, are preset in the instrument. The long-life battery lasts between 3 to 4 years, depending on usage. While the analyzer carries a warranty of 2 years, the O2 sensor has a 1.5-year warranty, and all other toxic sensors carry a 1-year warranty.

Testo is committed to providing prompt and efficient service, and for this purpose, there is a service and calibration laboratory set up at its headquarters in Pune.
