All Particle Counter Categories - Learn the Basics Here...

Here is a breakdown of the particle counter categories.  All particle counters use optical technology, either laser, glancing light, white light, scanning optics or conventional microscope lenses and detect particles from either the air, a liquid or a surface.  Cleanroom and critical environments generally use airborne and surface particle counters.  Airborne laser particle counters can be divided into how they are used: handheld, portable or remote (dedicated).

You can walk around with a handheld and take samples just about anywhere.  A portable laser particle counter is bigger and heavier with more features, can be carried to a location and set on a cart or table to take samples.  A remote particle counter is permanently installed at a location where it can continuously monitor and send information back to a control terminal. Most airborne laser particle counters come with an array of options expanding their capabilities catering to industry specific needs.

Trying to compare particle counters throughout a list of all particle counters may be challenging since it includes such a large number of instruments.  Use these tables to narrow down to a category what you wish to compare.  There are always specialized instruments used in very unique situations that do not fit in any major category, but these are what we consider the most widely used types of particle counters.

> All Particle Counters / Optical Particle Counters
All particle counters use optical technology to count particles from a sample.  The simplest is a microscope for the user to manually count particles on a surface.  Others use a light source and optical circuitry that detects the size and number of particles based on the behavior of light when it reacts with the sample.

> Laser Particle Counters / Air Particle Counters
Most laser particle counters are also air particle counters.  They sample the air and use a laser with counting optics to measure airborne particle contamination. They are utilized in cleanrooms, minienvironments, FDA regulated critical areas and by indoor air quality specialists.
> Cleanroom Particle Counter
Cleanroom particle counters are NIST traceable and configured to read out particle size channels for  common standards such as ISO, Federal Standard 209E, EU GGMP, and British Standard 5295.  Cleanroom particle counters include the categories below.

> Handheld Particle Counters
You can walk around with a handheld particle counter, using it to find a location with high particle concentration - very useful in filter testing, mold remediation and cleanroom troubleshooting and clean room verification.
