Airborne particles are a significant concern in cleanrooms as they can easily contaminate the controlled environment. The presence of airborne particles can lead to possible product flaws, diminished production output, and health risks to personnel. Therefore, the continuous monitoring and management of airborne particulates using effective tools is imperative in cleanrooms. Would you like to know one such versatile tool that has recently gained immense popularity? If that’s a yes, this post introduces you to the tool and helps you understand different aspects of its application, impact, and guides you through the best practices of using it.

Get Introduced to Cleanroom Particle Counters

Particle counters play a significant role in overseeing and preserving the purity of controlled environments, such as cleanrooms, laboratories, and manufacturing sites. These tools are specifically engineered to measure and count airborne particles, verifying adherence to designated cleanliness benchmarks. The working of these tools is simple and straightforward. They function by drawing in air samples via a sensor or detector. This mechanism enables the device to quantify the quantity and size of particles within the air. The information obtained from the particle counter is then displayed on a screen or stored digitally, enabling the user for future analysis and documentation.

Particle counters that operate on the light scattering principle identify airborne particles by their interaction with light. Essentially, these devices release a light beam into a designated sampling zone. When particles traverse this beam, they deflect the light variably. The device meticulously evaluates this deflection or scattering pattern to understand both the size and density of the particles present in the air.
