On-Board Emission Monitoring System (OEM-2100)

On-Board Emission Monitoring System (OEM-2100)

The OEM-2100 system can be installed in a matter of approximately 15 minutes on most motor vehicles.  It interfaces with the vehicle in three ways:  (1) it obtains power from the cigarette lighter; (2) it obtains engine data from an on-board diagnostic link found on most vehicles manufactured since the early 1990s; and (3) it obtains a small sample of engine exhaust using a sampling probe.  The device simultaneously records engine data and measures the concentration of several gases in the vehicle exhaust, including carbon monoxide, hydrocarbons, nitric oxide, carbon dioxide, and oxygen.  The instrument reports engine and emissions data every second and the data are retrieved for later analysis.
