A portable particle counter is one kind of small, hand-holdable instrument that measures the concentration and size of airborne particles in the atmosphere, and is primarily used to monitor air quality. It is an ideal tool for use in a cleanroom environment, manufacturing facility, laboratory, or by an HVAC system, providing accurate real-time information about particulate matter in the air such as dust, pollen, or pollutants. With advanced sensors and easy-to-read displays, portable particle counters ensure accurate and concise analysis for environmental monitoring and compliance with industry standards. Light and battery-operated, these devices are designed to offer maximum versatility while using them anywhere you go. From detection of contamination in sensitive environments to workplace air quality assessment, such a portable particle counter is a valuable tool for health and safety standards implementations.
