Modern models come with a built-in LCD that shows information on concentration, flow rate (approximately 0.1 cfm), temperature, and humidity, per ISO 21501-4 standards.
These devices are particularly ideal for pharmaceutical manufacturing, electronics, and places where high levels of cleanliness are essential. Indoor air quality and contamination spot checks can be easily performed, while USB connectivity enhances data transfer. Their high sensitivity and multi-channel monitoring capabilities enable accurate air analysis in various environments.
Definition and Purpose of a Particle Counter
A particle counter is an advanced instrument used to measure the size and number of particles present in air or liquid. Its purpose is to ensure contamination monitoring and environmental cleanliness, especially in the pharmaceutical, electronics, and cleanroom industries. These devices play a crucial role in maintaining air quality analysis, regulatory compliance, and product safety.
How Does a Handheld Particle Counter Work?
The laser beam passes through an optical block, which consists of mirrors and photodetectors. Sampled air is delivered by a vacuum pump to the location where the laser beam passes through and interacts with the particles. As a result of this interaction, the light scatters, meaning it changes direction in all directions, which is an essential part of particle detection.
Applications of Handheld Particle Counters
Handheld particle counters are used in various industries for air cleanliness and contamination monitoring. They are particularly employed in pharmaceutical manufacturing, electronics, healthcare, aerospace, and cleanrooms to check indoor air quality, assess the effectiveness of filtration systems, and ensure regulatory compliance. Due to their portability and high sensitivity, they are an ideal solution for spot-checking and real-time air monitoring.
