particle counters have been optimized for use in cleanroom environments. Setra has worked with many cleanroom managers to make their spaces compliant with current ISO standards. There are particle counter solutions to fit any budget or need. Setra's engineering team can design completely automated monitoring solutions for the highest level of control. Particle counters are used in cleanrooms for many reasons. In addition to ISO Certification, particle counters may be used for particulate source investigation, air filter testing, air quality compliance, and general manufacturing quality control. Setra's particle counter line includes **handheld models**, **benchtop models**, **remote models**, and **complete environmental monitoring solutions**. All Setra particle counters are made in the USA and are backed by Setra's legendary service, training, and generous warranty periods. [**Shop Cleanroom Particle Counters**](https://www.setra.com/product/particle-counters) # Why do cleanrooms need to be monitored for particle counts? Small particles that cannot be perceived by the human eye can cause contamination in cleanrooms. It is critical to keep these particles at a minimum. Particle counters allow cleanroom personnel to monitor the cleanliness of the room and quickly identify sources of potential particle contamination. Particle counters keep cleanrooms clean and safe while decreasing downtime and ensuring compliance. ## Cleanroom Particle Counter Solutions - All - Handheld - Air Quality Monitor - Remote Monitoring [ #### Handheld Cleanroom Particle Counter ](https://www.setra.com/product/particle-counting/8000-series-handheld-particle-counter) [ #### 7000 Series Air Quality Monitor ](https://www.setra.com/product/particle-counting/7000-series-aqm) [ #### 5000 Series Air Quality Monitor ](https://www.setra.com/product/particle-counting/5000-series-aqm) [ #### 7000 Series Remote Particle Counter ](https://www.setra.com/product/particle-counting/7000-series) [ #### 5000 Series Remote Particle Counter ](https://www.setra.com/product/particle-counting/5000-series) [ #### 8000 Series Handheld Particle Counter ](https://www.setra.com/product/particle-counting/8000-series-handheld-particle-counter?hsLang=en) If you are unsure what solution will work for your needs, or if you are interested in a custom, automated particle counting solution, contact a Setra Systems expert engineer to help find the best solution for your budget and requirements.

If you still need help choosing the right particle counter, contact the Setra engineering team. They will take the time to understand your budget, compliance needs, and cleanroom space to find you the best solution. [**Download the Selection Guide**](https://www.setra.com/hubfs/Resources/Particle_Counting_and_AQM_One_Page_Flyer.pdf) Do you really need a 1 CFM particle counter? Flow rate is important to consider when selecting a particle counter for a critical environment. The flow rate of a particle counter is the rate at which a pump draws air through the sample chamber, measured in cubic feet per minute (cfm). Two common flow rates for particle counters are 1 cfm and 0.1 cfm. Depending on the application, each flow rate can be valuable...

Particles are measured in micrometers (0.001 mm), also known as microns (μm). The naked eye can see objects as small as 50 μm, or roughly the thickness of a human hair. Typical organic particles (e.g. bacteria, mold spores, etc.) range in sizes between 0.5 μm and 10 μm. Setra’s particle counters and air quality monitors can measure particles between 0.3 μm and 25 μm in diameter.
