Portable Emissions Measurement System (PEMS) for nanoparticle counting and classification.

testo NanoMet3

The portable solid particle counter testo NanoMet3.Measure in real environmental situations.

Test any vehicle.Everywhere.

Onboard measurement of real driving emissions. Easy handling: One button measurement.

testo NanoMet3 is a Portable Emissions Measurement

System – PEMS to measure number concentration and

average diameter of solid nanoparticles in the size range

10 – 700 nm under real driving conditions.

It is compact, easily portable, rugged design and provides

on-line response over a wide concentration range. These

properties make it a suitable instrument for particle

number concentration measurements in non-laboratory

settings and even OBD instrumentation.

In addition to standard 100 – 240V AC power supply,

testo NanoMet3 can be 12 – 24V DC battery operated

for onboard and field measurements. The response time

is short enough to measure transient engine operation,

providing a complete data string with particle number

concentration, average size, lung deposited surface

area LDSA and calculated particle mass with 1Hz

resolution. The wide measurement range (diluted 1E4

– 3E8 pt/cm3) covers practically all exhaust emission

standards regarding particle number including the latest

requirements of EURO6.

Testo believes that NanoMet3 is therefore the ideal

candidate for in-use-compliance testing, as well as for

future PEMS type approval.

Portable Emissions Measurement System – PEMSfor nanoparticle counting and classification

PEMS matters

The increasing importance of accurate

and cost effective testing has become a

significant issue for the industry. A vast

experience in nanoparticle measuring

equipment for automotive, laboratory

and ambient applications enabled us to

develop a rugged, portable and cost-

effective solid nanoparticle counter. The

PEMS methodology and approach has

been recognized by many governmental

entities such as the U.S. Environmental

Protection Agency – USEPA and the United

Nations Framework Convention on Climate

Change – UNFCCC. Particle counting on

diesel light-duty vehicles is mandatory in

Europe for type approval through Euro 5b

since September 2011 and has been also

introduced for GDI technology through Euro

6 by September 2014. The European Union

and other countries worldwide will continue

to integrate particle counting into their

emission standards, especially since the

World Health Organization reclassified diesel

engine exhaust as ‘carcinogenic to humans’.

Moreover, the European Commission is

working on the approach for the technical

assessment of PEMS for particle number

emitted by light-duty vehicles. The oncoming

test procedure for EURO 6c standards

may include on-road measurements as an

extension of the PMP. Portable Emission

Measurement Systems (PEMS) have been

proven for certain applications to better

identify in-use performance of vehicles than

standard laboratory measurements. They

are designed to measure emissions during

the actual use of an internal combustion

engine vehicle or equipment in its regular

daily operation under real-world conditions.

Furthermore PEMS constitute a cost effective

solution to perform in-service testing of

heavy-duty engines: rather than extracting

the engines from the vehicles and then

installing them on an engine dynamometer

to run their official regulatory cycles, the

vehicles are equipped with on-board

emission measurement systems and tested

during their real in-use operation.

Measurement principle

When the sampling point of the PEMS during

Real Driving Emissions is at the outlet of

the tailpipe, the volatile substances may

condense into nanodroplets, which can be

detected as particles together with non-

volatile solid particles. To measure only

the solid particle fraction, it is necessary to

condition the sample thermally to remove

the volatile fraction. NanoMet3 features

a separate sample at the source and

conditioning of the exhaust probe according

to Testo patented Thermo-Dilution principle,

which is fully PMP compliant.

The portable system is completed with

Testo proprietary Diffusion Size Classifier

technology, a new sensor for measuring the

number concentration and average diameter

of nanometer sized particles. Since its

measuring principle uses electrical charging

to count particles, it not only enhances the

quality of the global measurement, but also

the cost of acquisition and costs per test are

significantly lower. Hydrocarbon emission

measurement will no longer be affected by

butanol contamination in the testing room,

nor will it be influenced by contaminated air.

Raw data can be stored in internal HD, exported by SD-card or directly read by a host computer.
