ANALYZER Particulates The PM-300 device enables real-time measurement of the size of particles emitted by internal combustion engines in 100 nm increments down to 300 nm. Exhaust is drawn through the analyzer through a heated sample line and a temperature-controlled, multistage mini diluter system equipped with high-precision mass flow. It generates a line of curves, each representing a specific particle size over the full operating range of the instrument. Analyzer is designed for stationary, portable and in-use, on-road applications. Sensors Inc.; 734/429-2100; www.sensors-inc.com
