Airborne Particle Counters

Setra’s particle counters are ideal for end-users who operate and maintain controlled environments seeking greater control over their spaces. In cleanrooms specified by ISO 14644-1, real-time continuous particle counters can detect potential contamination events before it’s too late to take corrective action.

Setra's Family of Particle Counters
How do you know your cleanroom is...clean?

If your facility is already monitoring pressure, temperature, and humidity, why guess when it comes to particles? Have confidence knowing your cleanroom is indeed clean all year long.

In this video, Jonathan explains the benefits of particle counting in places like compounded sterile processing (CSP) pharmacies where drug safety and patient health is at stake.

Comparison of Particle Sizes

How small are the particles that Setra’s devices can measure?

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.

What can a non-viable particle counter do that viable air sampling cannot?

In most hospital pharmacy cleanrooms, standard operating procedure includes sampling of air quality for viable particles (i.e. particles that include or are composed of microorganisms). These tasks are traditionally executed with an air sampler containing agar strips or simply by placing agar contact plates on... Read More
