Product Details

The Engine Exhaust Condensation Particle Counter 3790A (EECPC) fully meets all proposed PMP requirements for Euro 5 and Euro 6  regulations, as well as Euro VI. The Model 3790A builds upon the proven rugged, reliable, highly repeatable performance of TSI's second generation butanol CPC technology. The Engine Exhaust Condensation Particle Counter 3790A incorporates new improvements and performance features, such as anti-spill/anti-flooding design, condensate removal system, removable saturator for maintenance ease, USB communication interface, and more. The Model 3790A has a lower particle size detection limit of greater than 20nm to meet the PMP's requirement for eliminating measurement of volatile and semi-volatile nanoparticles formed by nucleation of gaseous compounds.

The TSI Models 379020A Rotating Disk Thermodiluter and 379030 Thermal Conditioner can be used with the EECPC to eliminate nanoparticles formed by condensation of volatile compounds found in engine exhaust, as required in GRPE/PMP draft regulations.


 Features and Benefits  

  • Meets the PMP lower particle size detection limit at the defined D 10 , D 25 , D 50 and D 90 counting efficiencies
  • Achieves a linear response to particle concentration from 1 to 10,000 particles/ cm 3 with R 2 >0.95
  • Achieves a counting accuracy of ± 10% against a traceable standard
  • Operates under full flow conditions using single particle counting
  • Calibration is in full compliance with PMP
  • Achieves readability of 0.1 particles/cm 3
  • Internal pulse-height monitor to indicate measurement quality
  • 10 Hz data rate for modal analysis


  • Diesel and gasoline engine emissions testing

Included Items  

  • Aerosol Instrument Manager® software

Resource Center

  • Can the CPC be operated with different carrier gases?
    Yes, but only inert gases.
  • Is the counting efficiency for each CPC determined individually?
    No. The CPC efficiency curve has been determined by testing a statistically valid number of CPCs and averaging the results to obtain the curve published in the product literature. Variation between units is very small.
