Designed to measure total solid particle number concentrations directly from the tailpipe, whether in the field or during in-use testing.
Building on the proven, regulatory-compliant Nanoparticle Emission Tester (NPET 3795), the High-Concentration NPET supports a wide range of emission sources, including internal combustion engines, gasoline- and diesel-powered vehicles, and biomass power plants. Its robust, user-friendly design makes it ideal for use by researchers, regulatory inspectors, and maintenance personnel.
Equipped with a built-in catalytic stripper that removes volatile particles, the High-Concentration NPET enables accurate measurement of solid particle emissions only. Based on the same unique design principles as certification-grade instruments, it delivers laboratory-quality particle counting in real-world environments — and is capable of handling emission levels beyond certification limits, such as those upstream of after-treatment systems, upstream and downstream of Diesel or Gasoline Particle Filters, cold start emissions or biomass combustion emissions.
The High-Concentration Nanoparticle Emission Tester is suitable for a variety of applications, including:
