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.

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.
