Abstract The report describes sensors and systems developed to provide precise measurements and readout of subsidiary emissions consisting of CO2, CO, H2O and O2. This report describes the use of various types of semiconductor materials for discriminatory sensing of various pollutant gases; a superior and unique semiconductor method was used, based upon the advanced state-of-the-art Brady Array bulk-effect humidity sensor. The theory of sensing by interstitial means and Ligand field theory are discussed. Material selection and sensor construction are described. The system was designed to facilitate direct readout of all channels via individual analog metering. In addition, outputs of 0 to 1 VDC were provided for online computer feed. The system was equipped with a stack sampling probe, filters and pump to provide full and complete stack sampling and measurement capability.
