NITROGEN OXIDE ANALYZERECO PHYSICS CLD 64• Compact design• Internal ozonegenerator andscrubber• Molybdenum or CLD 66steel converter forNO X detection• Four freelyselectable measurementranges CLD 64• Operation andcontrol via keypador personal computer• Mobile DC operationCLD 62Application examplesMeasurement ofpollutants (fixedand mobile stations)Outdoor NO 225 ppm monitoringSeries checks andquality controlEfficiency control on100 ppm DeNO X installationsTotal nitrogenmonitoring (TN)5000 ppmThe new CLD 64 nitrogen oxide analyzer is the economicalsolution for the continuous measurement of NO, NO 2 and NO Xconcentrations even in the low parts per billion!Outdoor NO 2 and NO Xmonitoring.We show you even smallestvariationsFor years ECO PHYSICS has been oneof the leading firms in pollutant measurement.Our analyzers come into use,wherever concentrations of nitrogen oxidecompounds have to be measured.Either integrated into entire productionprocesses and systems, or asstand-alone devices in monitoring stations,they continuously deliver the exactNO, NO 2 and NO X values you require.The design of the instrument isoptimized for rack mount and standaloneapplications.User-friendlinessThe development of an ECO PHYSICSanalyzer always includes full user comfort.The user can adapt the operationaccording to his needs and applicationsby selection of predefined settingsvia the keypad and remotely from a PC.Warning and error messages aredisplayed coded and in full text. Theanalyzer guides the user step by step toreturn to normal operation.Maintenance simply means annualreplacement of filters and membranesbesides the consumables required byspecial sampling conditions.Quality controls inproduction processes.Mobile measurementstations.Economical solutionThe CLD 64 fulfils the requirements ofoutdoor NO 2 and total NO X monitoringin fixed or mobile stations. Detectingand monitoring of smallest variationsof NO/NO X concentrations is oneof the key features. The fast responseand lag time in less than a second isunique of its class.NO 2 and total NO X is measuredby molybdenum or an optional steelconverter.Easy calibrationCalibration is quickly and automaticallycarried out. This extremely useful featureeliminates the potential risk of erroneouscalibrations.Compact and modular designThe CLD 64 is the most compact unit ofits class. Thanks to the totally modularlayout and integrated ozone generatorand scrubber it is designed for a multitudeof applications.
