Profile: Boston MicroSystems, Inc. develops and manufactures advanced chemical detection systems. We have developed a diesel exhaust emission sensor capable of long-term reliable detection of nitrogen oxide at levels of 1 ppm, sub-second response time, and sustained operation at temperatures greater than 500°C. This product is capable of meeting the needs of the automotive industry for a diesel engine nitrogen oxide emissions sensor that can be used for both on-board diagnostics and emissions reduction. We have also developed a smart sensor for detecting important pollutant gases that can function in the harsh conditions found in engines, furnaces and smokestacks.
