Handheld units are quick and
easy to take on the spot measurements of particulates. A handheld airborne particle counter
is good
for troubleshooting and verification.
Do You Need to Buy an Airborne Laser Particle
Counter?
Are you still uncertain about what exactly you need?
Our industry experts can
help you determine the proper equipment ...and even help you
learn to use it.
Portable,
Benchtop or Cart
Systems are ideal for continuous
monitoring of an environment with report printing capability or clean-room certification.
Remote particle counters are
permanently installed in a monitoring system and provide dedicated
continuous data from one location.
We made our comparison charts to help you choose
which kind of airborne particle counter you need. You will find that
portable particle counters are the most versatile, yet most
expensive. The Handheld air particle counters are a
little less expensive but have fewer features. The remote
particle counters are least expensive per unit, but may require a
more costly system depending on your needs. A lower price
solution for multiple remote sensors may be the universal
sequencing manifold,
though performance does not match that of using individual dedicated
remote sensors.
In our comparison charts we take a look
at all the features of air particle counters
to give you unbiased industry expert reviews on the best available
airborne laser particle counters. Our Industry experts have put
Lighthouse,
IQAir,
Climet,
Fluke,

Met One air particle
counters up against each other for quick reference on features,
applications, price and pro's / cons of each model. Our team of
industry experts has years of working knowledge with
cleanroom, indoor air quality and
mold or dust particulate
counters and will help educate you on what air particle counter is
right for your application.
Offering a combination of handheld and
remote particle counter features, the portable particle counters
provide a complete continuous real time monitoring system in a box
you can carry to location or put on a cart.
These are also known as dedicated
sensors. A remote particle counter is made to install in one
location and provide non stop contamination data and alarming to a
Remote Terminal Unit (RTU) or Area Control Unit (ACU) which
communicates with a central control room with host computers for a
Supervisory Control & Data Acquisition (SCADA) system, Facility
Monitoring System (FMS), building automation, or Facility Management
System (FMS).
Extend effective coverage of a remote
particle counter. Usually used within part of a large
monitoring system for minienvironments or process tools. A
manifold connects several probes to one particle counter, collecting
samples from one probe at a time. Ideal for documenting
trends. Multiplex sequencing manifolds require careful
planning. Depending on how probes are installed, they may
allow gaps in data collection.
Unlike liquid or surface particle
counters, air, airborne or sometimes called rosol particle
counters suck in a sample of air and test it. Airborne particle
counters use a laser or white light shining across the air sample,
onto photo detection electronics. The light is either absorbed
or reflected by particles in the air. The light reacts in a
pattern depending on the size of the particle floating in the air
sample. Photo detection electronics can interpret this pattern
and thus find the size and number of particles.
Air particle counters can generally
detect particles as small as 0.2 microns or as large as 25 microns.
Airborne particulate contamination that falls into this size range
include pollen, mold spores, house dust mite allergens, bacteria,
cat allergens, suspended atmospheric dust, cement dust, fly ash, oil
smoke, smog, tobacco smoke and soot. Gaseous contaminants and
viruses are too small to be detected by air particle counters.
Air particle counters have a variety of
uses. Residential and commercial Indoor Air Quality (IAQ)
deals with mold remediation, sick building syndrome and general
health concerns. Even though the air in commercial or
residential buildings may be at a healthy level of cleanliness, to cleanroom professionals, these are considered dirty environments.
Particulate contamination level of indoor breathing air will
generally depend on the pollutant levels of nearby outdoor air.
A decent contamination level for healthy indoor air can be several
hundred thousand particles per cubic foot. An excellent level
of cleanliness for indoor air would be under 100,000 particles per
cubic foot, comparable to a clean room of the "dirtiest"
classification.
Indoor
Air Quality professionals and
enthusiasts can use
airborne laser particle
counters to not only evaluate the
contamination level, but also find the source of contamination in
order to remove it. Cleanroom professionals may use the same
technique to find leaks or contamination sources in their cleanroom.
Some air particle counters can be used to verify the effectiveness
of a cleanroom while others can be used to
certify the
classification of a cleanroom or
critical environment.
Dedicated or remote air particle counters are important to
industries that must constantly monitor contamination levels within
a facility.
