NOx emissions require increasingly strict, continuous measurement reporting with high sensitivity and accuracy. However, traditional measurement technologies lack precision and speed and are susceptible to cross-interference effects from other gas components in the sample. Operators are also challenged to find robust measurement solutions with high availability and reduced maintenance and calibration requirements.
Emerson offers plug and play continuous NOx gas analyzers to help industrial plants prove compliance with environmental regulations, satisfy the mandated availability and meet reporting requirements. Utilizing a wide range of technologies, including Chemiluminescence Detection (CLD) and laser absorption spectrometry, these analyzers measure low concentration of NOx with very fast response times, free of the influence of other gas components in the sample. They are also available in a half and full rack enclosure, allowing easy replacement of legacy analyzers.
