An audit for the Environmental Protection Agency of vehicle exhaust emission measuring instrumentation currently in use at vehicle inspection and maintenance stations was conducted. Calibration gas standards were introduced into the instruments and responses recorded. Functional checks of the instruments were also made and information on instrument reliability and calibration procedures was collected. Results generally showed the instruments to be in good condition with readings within 6 percent of the standard gases for both hydrocarbons and carbon monoxide. Graphical and statistical analysis of the results showed significant variations in the measurements at only a few locations. Although the basic instrumentation at each station was very similar, the degree of computer automation and instrument calibration procedures varied widely from program to program.
