Ambient Level Multi-Gas Analyzer
The Cerex HOUND series are portable multi-gas analyzers developed to detect part per billion (ppb) to percent level concentrations of multiple gases within a mixture. The HOUND produces laboratory quality results in real-time using ultraviolet light absorption - similar to traditional infrared detectors, but features lower detection limits on many human health hazards and does not interfere with water vapor. All HOUND series analyzers come standard in a weather-resistant case with an integrated display, active ambient air sampling, and wireless communication. The FR versions are well suited for smoky or dusty environments with a faster sample rate and replaceable glass fiber sub-micron sample filter.
hermo Fisher Scientific Model 42iHL - NO-NO2-NOx Analyzer
This NOx monitor by Thermo Environmental generates three continuous signals: NO, NO2 and NOx. All three ranges are independent and have available outputs at the back of the analyzer. Meets USEPA requirements for RFNA-1289-074. The i series of analyzers also allows for ethernet connections. The Thermo 42i-HL can function as a datalogger and has enhanced diagnostics over its predecessors. The 42iHL also has dual range capabilities.
NOx analyzer
NO, NO2 and O2 on the inlet to an SCR.
NOx and O2 on the inlet to an SCR.
The gas stream contains ammonia, nitrogen oxides and in some cases sulfur dioxide . The NOx analyzer is a UV diode array process analyzer. Measuring the complete spectrum of the stream continuously and instantaneously.
The full spectrum advantage
The figures below show the absorbance spectra of the DeNOx process stream components,. The absorbance features overlap, therefore, a full high resolution spectral analysis is essential. High accuracies at a relatively wide dynamic range can be achieved due to the sharp absorbance features of the DeNOx stream component
The system uses an aspirator driven extractive sampling system with a heated umbilical sample line. The sample flows through the absorption cell and the oxygen sensor in series. Long sample lines are avoided, minimizing the normal sample losses associated with sample adhesion to interior tubing walls.
