I own a Heathkit exhaust analyzer. This unit only measures CO (%). To use it on autos WITHOUT catalytic converters, all you have to do is to stick the sensor tube in the tail pipe. If you have car with a catalytic converter, you must somehow stick the sensor sensor up stream of the converter in order to make a measurement. The accuracy of the unit is around 1 or 2 % when compared to the state's emmission testing center Sun IR analyzers. Jim Hoo Teltone Corporation Kirkland, Washington
