Specifications include, but are not limited to: Iowa State University is requesting bids for an emission measuring analysis system capable of multi-component measurements of NO/NOX, HC, CO, CO2 of diesel engines, ideally using the FTIR principle (raw rather than dilution). This unit would be used with ISU’s large Off-Highway Vehicle Chassis Dyno Lab with research and development testing and not for certification. The unit shall be a new, current model, under standard production by the manufacturer and be furnished complete with standard equipment and accessories as listed in the manufacture’s printed literature, plus the items below. All equipment and options must be factory installed. Bidding multiple options is strongly encouraged.; Measurements of NO/NOX, HC, CO, CO2 of diesel engines, ideally using the FTIR principle (raw rather than dilution); Be able to provide capabilities the unit would have to interface with external data acquisition equipment; Easy operation; Rate of output of the concentration of the different gazes should be enough for a quantify "steady state" emissions.
