Airborne Particle Counters

Particle countersare ideal for end-users who operate and maintain controlled environments and are 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. Cleanrooms, pharmaceutical plants, production plants, and even hospitals can benefit from using particle counters.

Setra Systems makes particle counters and air quality monitors for many applications. Download our particle counter comparison and selection guide to help choose the correct particle counter for your application.

The revisions toUSP 797reflect new science and evidence based on updated guidance documents, best practices, and new learnings. These updates to USP 797 become effective December 1, 2019.

Particle counting is important for maintaining USP 797 compliance. Bothviable and non-viable particle counters需要在太空中运行。Setra的粒子计数器是非可行的采样器，可以提供粒子计数的即时结果。

When selecting a particle counter, it is necessary to consider what building automation network it can communicate with. Examining the available options helps to ensure the particle counter will connect to your existing network. Setra's particle counters and air quality monitors can communicate locally and can also be easily integrated into a building automation and facility monitoring system with optional Wireless 802.11 b/g, Modbus RS485, or Modbus RS232 connections.

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.
