Cleanroom Cleanliness Assurance and Online Dust Particle Counter

Cleanrooms are widely used in industries such as electronics, pharmaceuticals, and food. The cleanliness of the cleanroom directly affects product quality and even relates to production safety; therefore, ensuring cleanliness is one of the core tasks. To maintain the cleanliness of a cleanroom, multiple measures must be taken:

Before entering the cleanroom, personnel must go through procedures such as changing clothes, washing hands, and air showering, aiming to remove dust adhering to their bodies.

When materials need to enter the cleanroom, they must also undergo cleaning and disinfection, and then be transported through a pass-through box to prevent impurities from being brought in.

In addition, the airflow organization design of the cleanroom is crucial. Air supply outlets continuously deliver clean air filtered by high-efficiency filters, "carrying" indoor dust out through return air outlets or exhaust outlets. They also maintain the positive or negative pressure inside the room to prevent external contaminated air from seeping in.

Daily cleaning and disinfection of the cleanroom’s floors, walls, and equipment are also required to reduce dust accumulation.

In the entire cleanliness assurance work, dust particles are the most core monitoring indicator — the number and particle size of dust particles in the air can directly reflect the cleanliness level of the cleanroom. Among cleanroom environmental monitoring systems, the most critical equipment is the Online Dust Particle Counter, which can accurately measure the concentration of dust particles in the air and the distribution of particles with different sizes, providing data support for judging whether the cleanroom’s cleanliness meets the standards.

The Online Dust Particle Counter under Fengtu adopts an advanced laser scattering principle, enabling rapid detection of dust particles with different sizes in the air. Its detection range covers common particle sizes from 0.3 μm to 10 μm, which can basically meet the monitoring needs of cleanrooms at all levels. The device is equipped with a high-resolution display screen that can show detection data in real time. It also supports data storage, capable of storing a large number of monitoring results, making it convenient to query and analyze data later.

In addition, this counter has excellent portability: it is lightweight and easy to operate, allowing staff to easily carry it to different areas of the cleanroom for mobile monitoring. It can also be fixedly installed at key positions to achieve continuous monitoring. After strict calibration and testing, the device’s stability and accuracy are guaranteed; even in long-term use, the detection data can remain reliable, providing solid technical support for the cleanliness assurance of cleanrooms.
