The Future of Dust and
Particle Monitoring
Dear readers,
I am delighted to find you interested in our Enviro Product Line.
Measuring and assessing particulate matter within the
ambient air is of prime importance: Limit values set by the
World Health Organization (WHO) for human health
protection are exceeded worldwide every single day.
In highly congested urban areas in particular, the degree of
contamination is clearly above those limit values with a serious
impact on all those many people subjected to it. In contrast to
gaseous airborne pollutants, no minimum threshold can be
scientifically defined for fine dust beneath the size of which
such dust does not have any further relevance to health. As a
consequence, it is our duty and responsibility to reduce
particulate matter contamination within the ambient air to a
level that is both technically feasible and cost-efficient at the
same time.
For more than 20 years my work at the Institute for
Environmental Protection of the Berlin Technical University
focused on measuring and assessing airborne pollutants.
Today, different measuring principles and techniques for the
determination of atmospheric dust are used in research and in
applications: gravimetric sampling (high-volume and lowvolume
sampling), beta dust monitors, nephelometers,
thermographic, electrostatic and optical methods. Each of
these technologies has its advantages and disadvantages, as
well as its specific range of applications.
Over time, however, a lot has changed: The measuring tasks
have become more demanding and consequently the
requirements on the necessary measuring technology as well.
If in the past monitoring was mainly about staying within dustrelated
limit values; today, root cause analyses and finding the
sources of fine dust contamination have become the primary
targets. Only by being able to properly identify the source of a
specific particulate matter contamination, appropriate, costefficient,
and long-lasting, effective initiatives can be started in
politics.
It is not sufficient to learn tomorrow about today´s fine dust
contamination values; people are entitled to get real-time
information about the current fine dust contamination. In
addition, mean values on a 24-hour basis do not offer enough
information for a precise identification of the contamination
sources.
Atmospheric processes, such as vertical and horizontal
transport and compound processes that have a fundamental
influence on the fine dust contamination within the ambient
air, obviously show lower time scales (minutes to seconds). As a
consequence, measuring technologies with the following
characteristics have become indispensible for today's
measuring tasks:
Dr. Markus Pesch
Technical Director
GRIMM Aerosol Technik GmbH
Continuous measurements with a high temporal
resolution (a few seconds up to 30 minutes)
Information on the particle mass fractions PM10, PM2.5
and PM1 (to monitor the current and future limit values).
Determination of the particle size distribution (to judge its
relevance to health and precisely identify the source).
Maintenance-free, reliable measuring technologies
involving little labor (cost-efficiency).
High sensitivity and low levels of detection (reliable
determination even at low dust contamination of but a few
µg/m³).
Our GRIMM optical fine dust measuring equipment was
designed to meet all the above mentioned requirements.
All our Enviro systems are equipped with the same optical
chamber permitting a precise and reliable single particle
determination. This optical chamber is currently operating in
more than 3,000 devices worldwide and has proven its
quality and superiority by successfully passing the European
directives for PM10 and PM2.5. With the ability to
simultaneously measure dust mass fractions PM10, PM2.5
and PM1 as well as the particle size distribution in up to 31
size channels (simply by switching measuring modes), the
operator is well-prepared for all present and future dust
measurement tasks and specific root cause analyses.
In my capacity as Technical Director of the GRIMM company, I
will strive for a continuous development of measurement
technologies meeting the highest technical standards and
setting the benchmark for what is possible today. Rest
assured that through the combined know-how of our
engineers and scientists - from the service department to the
product development department to R&D - we will provide
top quality in all aspects of our product range and services.
Our line of Enviro products is currently employed in various
fields of application worldwide. I look forward to welcoming
you as a new future GRIMM customer.
Yours truly,

GRIMM EDM 365
(pages 12-13)
With our EDM 365 we set new standards in environmental monitoring! Compared
to the portable EDM 107 this stand-alone mini shelter can operate on a continuous
basis providing the PM-values of all dust fractions - including semi-volatile
compounds -, the GPS position, wind speed, wind direction, precipitation,
temperature, and humidity. Even data on nano particles down to 25 nm (mean
diameter and total counts) are available and indicative gas sensors can be added as
well. All values are automatically transmitted to the data logger or to the www.
Stationary Dust Monitor
GRIMM EDM 180
(pages 8-11)
The EDM 180 Environmental Dust Monitor is a 19" rack-mounted instrument
specifically designed for use inside protective housings in conformity with the
existing EPA regulations for dust monitoring. As an option, this system can deliver
up to 31 particle size channels within a time resolution of 6 seconds. No semivolatile
compounds are lost in the process. Approved and officially certified it is the
ideal solution for government use in PM monitoring.
Wide Range System
GRIMM EDM 665
(pages 14-15)
Flagship of our Enviro line is the Wide Range Aerosol System EDM 665, the ideal
combination of optical and electrical mobility particle sizing. It has been designed for
environmental research with a perfect overlap of both technologies in the measuring
results. This system automatically determines the size distribution of all aerosols
ranging from 5 nm to 30,000 nm in more than 70 different size channels. In addition,
it is a stand-alone system with an automatic sample air dehumidification and
moisture extraction system incorporated. Thanks to the integrated air conditioning
providing uniform operating conditions, the system can be run unsupervised for
extended time periods necessitating but one single minor intervention a month.
Meteorological sensors as well as GPS and wireless transfer are optionally available.

Measuring Principle
TSP
PM 10
AIR FLOW:
This inlet was designed to meet the requirements defined
at the Johannesburg convention. Sample air at a volume
flow of 1.2 liter/minute is directly fed into the measuring
cell by passing through a TSP (total suspended particles)
head and the probe inlet.
Thanks to this unique principle none of the GRIMM
instruments need any size-selective sample inlets as do all
other dust monitors on the market.
OPTICAL SYSTEM:
The sample air is then passing through the heart of the patented GRIMM spectrometer cell that has
been designed as a single particle detection and counting system. As a consequence, we can
guarantee that every single particle is measured by the instrument.

The optical system was optimized in such a way
as to ensure that the refractive change (color) is
negligible. Even in the nano size range the
sensitivity across the size channels an excellent
sensitivity is ensured.
All particles (aerosol) passing through the measurement cell are classified by size distribution into 31
channels. Based on this size distribution principle, we obtained the European Equivalence Approval
for PM10 and PM2.5 as well as the US-EPA Approval for PM2.5.
The required figures for PM 10, PM 2.5, as well as for the suggested PM1
are arrived at by multiplying the
obtained count concentrations with the corresponding specific density factors then to be added to the
total masses of each PM channel. This is all done automatically by the instrument.
One of the main problems in measuring ambient air is high humidity. To prevent moisture or small
water droplets from being measured the probe is usually heated to minimize this effect. As an
unwanted side effect, semi-volatile compounds such as nitrates, sulfates, etc. are vaporized before
they can be measured.
Instead of heating the probe, the GRIMM EDM isothermically extracts the humidity by dry air or Nafion
tubes, a process patented by GRIMM. Scientists all over the world agree that the semi volatile
compound (SVC) fraction normally produced by manmade processes (industrial areas, automotive,
combustion, etc.), can amount to 20-50% of the total dust. In addition to the PM + PM + PM
values, this contribution can be determined as an SVC fraction by a GRIMM EDM 365.

Benefits of GRIMM EDM Monitors
FOUR VALUES SIMULTANEOUSLY
The GRIMM EDM 180 is the only commercially available fine dust monitoring unit in the world,
approved for PM 10 & PM 2.5, capable of measuring PM 10, PM2.5 and PM1
in µg/m³, as well as TC (total
particles) in p/l at the same time. Measurement updates of all these values are provided in 60-
second intervals and in combination with optionally available meterological sensors identifying the
origin is facilitated, thus permitting a better risk assessment.
LITTLE MAINTENANCE REQUIRED
All GRIMM Environmental Dust Monitors are designed in such a way as to require as little
maintenance as possible; a field system check with a foolproof test kit should be largely sufficient.
ISO 9001 stipulates that calibration of the spectrometer of that system is calibrated once every 12 to
18 months. Instead of calibrating several instruments - one for each PM value - there is but one
GRIMM instrument needing calibration.
REMOTE SERVICE, CONTROL & DATA ACCESS
Output data from the instrument can be directly transmitted to your environmental network, your
Intranet or the world wide web by using our Data Logger 1142.M5 (or the integrated German
GESYTEC protocol).
Scientists or environmental engineers thus gain access to the data from anywhere in the world via the
WWW, by SMS or other data transfer system. Worldwide access to the service interface of our
instrument for the purpose of preventive maintenance is possible as well. A fully automatic self-test
and control system monitors the performance of the instrument and reports possible errors. All this
results in a considerable reduction of the total cost of ownership!
The GRIMM data web page (see page 15) gives every customer the chance to look into his
measurement results in real time from anywhere.
COMPACT SOLUTION
Apart from the fact that our instruments needed to be designed to include all necessary accessories
one of the major objectives was the minimization their dimensions.
Focusing on arriving at the smallest possible instrument size while not compromising reliable
measurements the instruments we can offer compact and handy solutions for your everyday work.

Model 1.320 NanoCheck Particle Sensor:
With optically measuring technologies reaching their limit
at some 150 nm, we developed the NanoCheck 1.320 to
be used in combination with our EDM 180. This unit closes
the gap down to 25 nm and provides information about
the number and mean size of nano particles below the
optical detection limit. It comes in a rack mounted version
as depicted on the right.
The upcoming 1. 321 NanoCheck
Sensor will be able to
monitor these nano particles in size ranges of 4 different
classes.
System 1.320/1.321 is a great add-on to the EDM 180 with an integrated 1142.M5 Data Logger and a
touch panel. Get the benefit of being able to see ultrafine particle values in real-time on the display.
Meteorology
Sampling
NEW Meteorological Sensors:
Our new meteorological digital sensor program has now become available for
the EDM 180/ 365/ 665 instruments as an option. It replaces the existing
analogous sensors and upgrades the EDM 180 to benefit from this new digital
technology
Three versions are available:
Model 157L for temperature, relative humidity and ambient pressure.
Model
158L adding wind speed and wind direction to the features of model 157L
Model
159L topping model 158L with an additional ultrasonic sensor for
precipitation (rain and snow).
Please note that apart from the 184L, sensors 158L and 159L require the 1142.M5 Data Logger as
well. When upgrading from the standard analogous sensors, the 184L sensor connection kit is always
required.
Automated Filter Sampling:
To obtain specific samples for laboratory testing (to determine the
chemical composition for instance) of dust exceeding a certain value, we
also supply intelligent filter sampling systems. Sampling time and
sampling intervals are computer-controlled and can be set / modifed by
the end user, which is true for the filter change of the 14 or more filters
(25 to 47 mm).
Another useful feature of the GRIMM instruments.
NEW Outdoor Housings:
To guarantee an accurate data acquisition in conformity with worldwide
governmental regulations, we supply environmental 19" protective housings for our
systems featuring integrated data acquisition systems and A/C. For detailed
information ask for our GAS catalogue.

Calibration & Quality
How are Grimm Aerosol instruments
calibrated
Each manufacturer calibrates his systems differently.
Since no worldwide standard for the calibration of
aerosol spectrometers exists, GRIMM developed their
own in-house calibration process. This process has
been validated by Government Departments and is
based on a real-time comparison and adjustment
between a “reference unit” and the unit to be
Quality End Control
Grimm Calibration Process
Calibration between the candidate and the reference unit
makes use of a "Grimm Calibration Tower" (shown on the
left): The computer-controlled process itself is completely
automated. Dolomite dust is used for our calibration aerosol.
Dolomite dust is anoxic, not hygroscopic, polydisperse and
very stable during storage. In addition, Dolomite dust covers
the entire sizing range for all Grimm spectrometer from
approx. 0.2 μm to >30μm. Due to the fact that both the
reference unit and the candidate were manufactured
identically, the Dolomite dust has to produce identical results
in both spectrometers. The dust is injected at the top of the
cylindrical calibration tower by particle-free compressed air
and homogeneously dispersed within the entire tower. Up to
three calibration candidates and one reference unit are
attached to the bottom of the tower via identical aerosol
inlets. A reverse flow of particle-free compressed air from the
bottom to the top of the cylindrical tower guarantees a welldefined
and reproducible aerosol particle distribution during
the whole calibration process.
All Enviro Systems are subjected to a long-term test by operating them complete with sampling pipe
and weather housing (or outdoor rack) for a week in an outdoor reference system. During this time
period, all functions are tested; humidity and temperature sensitivity of the probes, the humidity
controlled mixing service or the temperature regulation, for instance. The data thus obtained are
stored for each delivered unit.

Digital Meteorological Sensors
Our new digital meteorological sensor program is now available for all GRIMM
EDM systems and has already become a standard in the EDM 365 product
range. This 158L model delivers information on temperature, relative humidity,
pressure, wind speed and wind direction.
The optional model #159L combines the features of the #158L with a ultra sonic
sensor for rain and snow information.
1.320 NanoCheck Sensor
Since optical measuring technologies reach their limit
with particle diameters of less than 150 nm, we
developed our NanoCheck 1.320: A device closing
this gap down to 25 nm and providing information on
the number and mean size of these nano particles.
The combination of our optical spectrometer with the
NanoCheck delivers additional information on
ultrafine aerosols (soot particles from vehicle
emissions, for instance) and mechanically created
aerosols (such as tire and brake abrasion). AS a
consequence, the NanoCheck add-on in
combination with the EDM 365 represents the perfect
tool for assessing air quality at road sites. Just think of
the “Green Zones” currently set up all over the world,
which can now be properly evaluated by such an
instrument combination.
365 Gas Sensors
This indicative sensor was recently added to the GRIMM
product portfolio to give customers the opportunity of
acquiring an even more extensive environmental monitoring
system.
The gas system can be equipped with 2 different toxic gas
detectors (CO, H2S, So2, NoX or Nh2) as well as a PID
sensor. This sensor can be linked with the above data logger
system to the EDM365.

Data Acquisition
1142.M5 Data Logger
Logger 1142.M5. This data logger is an all-in-one microcomputer
interface with integrated web server permitting an interactive
communication with the instrument based on TCP/IP protocols.
This logger can be combined with all GRIMM products adding the following features to our
instruments:
Extended storage of up to 4 GB, remote control, the possibility to combine information from GRIMM
monitors with data from various other sensors such as meteorology and gas probes. Data can be
transmitted in real-time to the world wide web, our GRIMM data base system, your web page or an
Intranet.
The GRIMM database system offers a range of possibilities for the remote administration and
configuration of your instrument from wherever you are and the data thus obtained can be presented
