A particle counter is a scientific instrument used to determine the quantity and size of small particles in air, liquids, or gases. It is commonly used in cleanrooms, pharmaceuticals, electronics manufacturing, and environmental research. A particle counter uses optical sensors or laser technology to detect fine particles in air or liquids and count the number of particles in a given unit (such as per cubic foot or milliliter). This provides information about how clean or polluted the environment is.
Modern particle counters can automatically collect and analyze data, which can be linked to control systems to help control pollution. Particle counters are used to ensure the quality of the production environment, especially in the pharmaceutical and semiconductor industries. They are also used for sensitive work in hospitals and laboratories. In short, a particle counter is a device that detects microscopic particles and plays a supporting role in verifying and controlling cleanliness standards.
