EMISSION TESTER

MODEL 3795-HC

PORTABLE AND ACCURATE FOR HIGH CONCENTRATIONS

Originating from the Regulatory Compliant NPET, the High Concentration NPET has been designed to measure total solid particle number concentration in emissions directly from the tailpipe. Measurements are derived from sources in-use or in the eld. Sources can be internal combustion engines, gasoline- or diesel-powered engines, or biomass power plants. Featuring a robust and user-friendly design, the High Concentration NPET can be used by researchers, regulatory inspectors, and maintenance personnel alike.

The High Concentration NPET derives from the basic and unique

design of the NPET 3795, which allows you to bring labortory-

grade particle counting to your worksite. With similar design to

instruments used in certication 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

certication levels, including the engine output upstream of the

after-treatment system.

Features and Benets

+ 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/cm

+ Selectable measurement modes:

– Real-time data logging for research

– User-dened protocols for reporting test cycle results

Applications

+ In-use diesel machinery compliance certication

+ Exhaust after treatment inspection and maintenance programs

+ Diesel Particulate Filter (DPF) retrot programs

+ Gasoline Particle Filter (GPF) characterization

+ Fleet emissions proling

+ DPF/GPF regeneration studies

+ Cold start emission measurements

+ Combustion emissions research (biomass, wood burning)
