NOx Measurement, CO Measurement

Fast, Stable, Repeatable, Accurate to 20 ppm

Measure NOx and measure CO (and other gases) by conditioning and modifying the signal from a sensitive wide range performance oxygen sensor.

  • Combustion Efficiency Improved
  • Pollutants Reduced

This technology provides a stable, repeatable and selective sensor at an economical value. It can be used in both automotive and industrial applications to improve combustion efficiencies and reduce environmental pollutants.

Figure 2 Figure 1Proven Successful

This combustion gas sensor technology has been successfully demonstrated at several large industrial companies. Figure 1 and figure 2 show that it can measure NOx to an accuracy of 20 ppm. The method is capable of measuring the combined response to NOx (NO+NO2) with minimal interference from CO and O2.

Automotive applicationsIndustrial applicationsPractical and Economical

Government and industry are looking for a practical and economical combustion gas sensor technology for both automotive and industrial applications. The current mixed-potential gas sensors demonstrate strong response to the presence of nitrogen oxide and carbon monoxide but lack stability, repeatability and selectivity. This technology provides these missing attributes.
