A cleanroom particle counter is a device that measures and monitors air quality through the detection and sizing of airborne particles in controlled environments, such as cleanrooms. This ensures compliance with industry cleanliness standards; sectors such as the pharmaceutical industry, the biotechnology industry, the microelectronics industry, and the aerospace industry require extremely low levels of contamination to be established. The device pulls air through a laser or light scattering mechanism to count and classify particles by size, usually measured in microns. Handheld, portable, and remote varieties are available, each suited for specific applications. Information on accurate particle counts maintains product integrity, supports contamination control, and validates cleanroom performance. Modern designs often feature data logging, real-time monitoring, and connectivity to central systems for comprehensive environmental management.
