Capturing the most accurate emissions from heavy-duty diesel trucks is possible through our portable laboratory, which conducts research on the road.

Mobile Emissions Laboratory

Housed in a 53-foot tractor trailer, the Mobile Emissions Laboratory, our heavy-duty mobile lab, represents a significant step forward in measuring “real-world” emissions.

Mobile Emissions Trailer Our trailer connects to a tractor rig and is pulled down the road. The truck’s entire exhaust stream is captured by a connector and transferred into the laboratory. Then our scientists quantify gaseous, toxic and particulate emissions using instruments that meet federal standards to measure gaseous and particulate matter during actual vehicle operations. Doing this gives our researchers a clearer picture of “real-world” driving emissions.
