Particle Counter Real-time Monitoring of Airborne Particulate Matter

Particle Counter can simultaneously measure the number of dust particles in six particle size channels in a single sampling and display their changes. It is primarily used for dynamic environmental monitoring in aseptic production areas of pharmaceutical companies, enabling real-time monitoring of the number and size distribution of airborne particulate matter. It is widely used in cleanrooms, pharmaceutical workshops, and electronics manufacturing, contributing to environmental quality control.

Particle Counter is a specialized device for real-time monitoring of air cleanliness. Its core function is to accurately measure the number and size distribution of suspended particulate matter in the air. The system primarily uses laser scattering technology. When airborne particles pass through the detection chamber, a beam of light emitted from a built-in semiconductor laser illuminates the particles, generating scattered light. The scattered light signal is received by a photodetector and converted into electrical pulses. The amplitude and number of pulses correspond to the particle size and concentration, respectively. Based on this principle, the system can synchronously count particles in specific particle size channels.

The application of this system is particularly crucial in the pharmaceutical industry. Aseptic production areas must meet stringent GMP cleanliness standards. Particle Counter enables dynamic environmental monitoring of Class A and Class B clean areas, reflecting real-time changes in particulate matter during production. The system typically features remote sensors with 316L stainless steel housings, capable of withstanding corrosive reagents used in daily cleanroom disinfection, and employs an isokinetic sampling head design to avoid interfering with unidirectional airflow. When the detected particulate matter concentration exceeds a preset threshold, the system triggers an audible and visual alarm, prompting timely intervention from operators.

A key feature of this system is its ability to simultaneously detect dust particle counts across six particle size channels in a single sampling operation. Common particle size channels include 0.3μm, 0.5μm, 1.0μm, 3.0μm, 5.0μm, and 10.0μm. Multi-channel simultaneous monitoring means that users can obtain complete distribution data for particles of different sizes with a single sampling action, allowing real-time viewing of the number and trends of particles of each size. This design improves monitoring efficiency and provides more comprehensive data support for environmental quality assessment.

In terms of data management and communication, the modern Particle Counter supports multiple transmission methods, including WiFi, Ethernet, RS485, and 4G wireless transmission. The system can upload monitoring data to a cloud platform or central control room in real time, facilitating long-term and short-term cleanliness trend analysis and remote fault diagnosis. Some models have built-in large-capacity data storage, which can temporarily save monitoring records during network outages and automatically re-upload them after network restoration, ensuring data continuity and integrity.

The system is designed for reliable long-term continuous operation. Core components such as the laser light source have a lifespan of over 30,000 hours. For large-scale deployment scenarios, the system supports modular networking, allowing a single vacuum pump to connect to multiple remote sensors simultaneously for multi-point synchronous sampling. This design reduces equipment costs and simplifies installation and maintenance, enabling the Particle Counter to meet the long-term monitoring needs of various clean environments, from pharmaceutical workshops and electronic semiconductor factories to food processing production lines.
