CO 2measurement module for testo 350 M/XLDirect CO 2measurement in flue gasA CO 2infrared sensor was designed especially for CO 2measurement. The dimensions of this sensor are identical to thetesto electrochemical measurement modules. Like the othermeasurement modules, the CO 2infrared sensor can be very easilyinstalled in the sensor slot of the testo 350 M/XL.Lasting value:Even measuring units already in use can be easily upgraded.Special attention was paid to the lasting value of testo 350 M/XL inthis respect.Diagram of the CO 2infrared sensorMeasuring gasReference receiverAbsolute pressuresensorOne sensor for all applications:A non-dispersive infrared-sensor (NDIR) is used in testo 350 M/XLfor direct CO 2measurement. This sensor is a Testo developmentwith a complete measuring range from 0 to 50 Vol.% CO 2 .The sensor works according to the one channel-double beamprocess: two infrared-receivers with two different optical filters arebuilt in a miniature cuvette (sample and reference filter).IR-emitterSpecial windowIR radiationFilterSample receiverCO 2displayAnalysingelectronicsP absdisplayOnly app. 4.27 µm radiation can pass through the sample filter.This wavelength is absorbed by CO 2. The reference filter on theother hand is permeable for a radiation of app. 4.0 µm. Noradiation-absorption by gases takes place in this radiation range.DetailsReference filterSample filterSafety:Reliable functioning and accurate measurements are guaranteedby self-diagnosis with the reference channel. Possible driftscaused by beamer wear or dirt are corrected automatically by thesensor.Additional checks or adjustments of this automatic drift correctioncan be carried out very easily by the user using the enclosedabsorption filter.For very high demands on accuracy, special calibration in a limitedmeasuring range can be made by the user with the cal gas.Availability:Two special windows are used for protecting the IR emitter, filterand receiver against corrosive gas components.All advantages at a glance:• Highly accurate measuring range of 0 to 50Vol.%• Not affected by absolute pressure influence and temperaturefluctuations• Robust and long term stability• Reliable measurement results by automatic monitoring function• Highly accurate due to easy reset and adjustment for specialmeasuring ranges• Highly accurate O 2measurement with testo 350 by eliminatingCO 2influence at high concentrations• Convenient Pitot tube measurement with automatic gas densityanalysis using testo 3503
