2 emissions are measured in pounds per hour using both an SO 2 pollutant concentration monitor and a volumetric flow monitor. For NO x, both a NO x pollutant concentration monitor and a diluent gas monitor are used to determine the emissions rate in weight per volume or weight per heat value (for example lbs/million Btu, lbs/ft 3, kg/kWh or kg ...
Emissions from all non-road engines are regulated by categories. [49] In the United States, the emission standards for non-road diesel engines are published in the US Code of Federal Regulations, Title 40, Part 89 (40 CFR Part 89).

A CATI PEMS being strapped down inside a vehicle. A portable emissions measurement system (PEMS) is a vehicle emissions testing device that is small and light enough to be carried inside or moved with a motor vehicle that is being driven during testing, rather than on the stationary rollers of a dynamometer that only simulates real-world driving.
