Regulators and researchers use TSI particle instruments for engine emissions research around the world. Our products help quantify and analyze particle emissions from light-duty and heavy-duty engines, for both on-road and stationary applications.
You’ll find TSI products used in the research and development of advanced internal combustion engines and after-treatment systems, like Diesel Particulate Filters (DPF) or Gasoline Particulate Filters (GPF). Our particle counters quantify the number concentration of aerosol particles. TSI particle sizers measure the size distribution of exhaust particles.
Our instruments allow measurements at the tailpipe, from the Constant Volume Sampler (CVS), or from other partial flow samplers. TSI’s fast sizer spectrometers may also enable high time resolution mass measurements of engine exhaust particles.
