Air Particle Counters - Choosing an Airborne Particle Counter
Are You Confused About Air Monitoring Technology? Read Our Air Particle Counter Comparisons and Reviews by Leading Industry Experts
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
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.
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.
