Request A Quote Related Products


The TSI Nanoparticle Emission Tester (NPET) Model 3795 is a portable, easy to use and cost effective instrument. It is designed to measure total solid (non-volatile) particle number concentration from vehicles, engines and other combustion sources. Featuring a robust and user-friendly design, the NPET can be used by researchers, inspectors, and maintenance personnel alike.

The standard version model 3795 serves specifically the needs of those who need to comply with the Swiss standard SR 941.242.

This high concentration model 3795-HC was designed to measure upstream and downstream of Diesel or Gasoline Particle Filters, cold start emissions or biomass combustion emissions.

Product Details

The High Concentration NPET derives from the basic and unique design of the 3795 NPET, which allows you to bring laboratory-grade particle counting to your worksite. With similar design to instruments used in certification testing, the built in catalytic stripper removes volatile particles to enable measurements of total solid particle emissions only.

This design is able to handle emission levels well beyond certification levels, including the engine output upstream of the after-treatment system.

FEATURES & BENEFITS

  • Direct measurement of particle number concentration using proven Condensation Particle Counter (CPC) technology
  • Sampling probe with integrated dilution to measure concentration up to 100,000,000 particles/cm³
  • Selectable measurement modes:
    • Real-time data logging for research
    • User-defined protocols for reporting test cycle results
  • Sampling probe with integrated dilution
  • Wide environmental operating range
    • -10 C to 40 C
    • 0 - 3,000m

APPLICATIONS

The Nanoparticle Emission Tester is suitable for a variety of applications, including:

  • In-use diesel machinery compliance certification
  • Exhaust after treatment inspection and maintenance programs
  • Diesel Particulate Filter (DPF) retrofit programs
  • Gasoline Particle Filter (GPF) characterization
  • Fleet emissions profiling
  • DPF/GPF regeneration studies
  • Cold start emission measurements
  • Combustion emissions research (biomass, wood burning)
