Are You Confused About Which Particle Counter You Need for Your Application?

~ We Helped Write the Cleanroom Classification Standards! ~

There is No One More Qualified to Determine Which Instruments You Need Than Our Panel of Cleanroom, IAQ and Filter Experts!

laser particle is the most authoritative website on the internet about particle counters. That's our goal.  And the way we achieve it is by finding knowledgeable professionals in the particle counter industry who contribute to this site.  Without bias, we present information collected from a variety of particle counter industry experts in order to help you understand and decide which particle counters are right for your application.

Most laser particle counter websites rely on you to know exactly what you want.  Some people do, but many people are faced with choosing an airborne particle counter armed with very little information.  That's where we come in.  This site is made to educate, using the knowledge of Indoor Air Quality (IAQ), cleanroom and particle counter industry professionals.

When choosing a liquid or air particle counter, the first objective should be to find one that performs all tasks you need.  From the navigation on the left, you can choose a category.  The information on that page will help you narrow down your choice.  If you are not sure, start with a broad category, like all particle counters.  As you learn more, you can work your way down through smaller categories.

If you are totally new to particle counters, here is some basic information to start you off...

What is a particle counter?

A particle counter is a sophisticated monitoring instrument that counts the amount of particulate contamination.  Modern particle counters detect contaminants from the air, a surface or a liquid.  Some examples of these particles can be anything from oil, metal shavings, dust, smoke, ash, mold, or other biological contaminants. surface particle counterThis information is very useful to professionals for determining how pure the air is for breathing, water treatment, producing food & drugs or microchips in a cleanroom.

A particle counter can be as simple as a handheld air monitoring instrument or become as advanced as remote or multiplex manifold sequencing clean room systems used for entire facility monitoring. Depending on the model type, particle counters can detect as small as 0.1 microns.  Nano particle counters are being developed to count even smaller particles.

Airborne Particle Counters

To familiarize yourself with the three most common packages particle counters come in, let's start with something familiar: air.  The three most popular kinds of airborne particle counters are handheld, portable and remote.

Handheld Particle Counters

handheld particle counterA handheld particle counter offers a convenient and portable way to test your indoor air quality, spot check or verify clean rooms and test air filter efficiency.  Small enough to walk around and hold in one hand, these types of particle counters are great for quickly finding general information about the air in one spot, then moving and checking another spot.  In this way, they can be used to locate a source of contamination.

If you're looking for a cost effective way to test your air purifier or air filtration system, we would suggest the entry level handhelds. These particle counters offer easy one touch monitoring and are very basic to use.

If you need more advanced IAQ or cleanroom features like verifying or monitoring particles, temperature, relative humidity, time stamp etc, we recommend the more advanced handheld models.

Do You Need to Buy a Particle Counter?

Are you confused about what you need?

Don't be intimidated - we have a panel of experts who work for most major particle counter manufacturers who will match you up with the best instrument... at the best price.

Portable Particle Counters

Portable laser particle counters are designed as a more complete instrument with more capabilities thenportable particle counter handheld, yet are still mobile. These portable particle counters can be set on a bench or cart and are used for certifying or continuously monitoring a cleanroom, can be integrated into your current facility monitoring system or used as a stand alone device.

Portable particle counters offer a list of features not found in your handheld particle counters. Some of these features include thermal printing, filter scanning, air velocity, differential pressure, temperature and isokinetic sampling of ambient air.  Some portable particle counters can even run other environmental sensors, acting as a hub for a complete environmental monitoring stand alone system.   Most portable particle counters have the ability to connect to a PC computer or network for archiving and analysis.

Remote Particle Counters

A Remote particle counter is used in a facility that needs to continuously monitor multiple locations. Sometimes called dedicatedremote particle counter particle counters, each one is an inexpensive, compact unit that continuously counts particles and sends information to a remote terminal or area control unit. Several terminals are controlled by a main control room.  In this way, remote particle counters are networked together and controlled from a centralized computer room. Using a remote particle counter system makes it possible to track facility wide contamination levels while integrating with other systems monitoring or control systems.  These systems are often called Facility Management Systems (FMS), Facility Monitoring Systems (FMS), Distributed Control Systems (DCS), Building Automation Systems, or Supervisory Control and Data Acquisition Systems (SCADA).

Whether you are dealing with complex systems or a simple handheld instrument you will need software to display, archive and analyze your collected data.  Software can vary from downloading and converting handheld data to industry specific analysis based on cleanroom classification. Software systems can sync up to Handheld, Portable and Remote particle counters depending on model and brand.

Now that we have discussed the types of the latest particle counters, take a look at the categories in the left hand navigation.  Take a stab (or rather a click) at one of the categories.  And see if any of the categories may include the kind of particle counter you need.  We strive to make our website easily navigated via equipment categories and manufactures.  Don't be afraid to jump into unfamiliar categories.  We've put information all over this site to help you make more educated decisions about particle counters.

We are continually striving to make this website an educational resource to you with unbiased comparisons and reviews from industry experts in the particle counter industry.
