Particle Counters & Air Quality Monitors

ISO 21501-4 and JIS B9921 Compliant Counters


A particle counter is an instrument that measures and counts the number of various sized particles in the air. Particle counters can be used to monitor potential contamination in cleanroom environments, to monitor indoor air quality (IAQ), and to ensure certification of ISO standards.


We offer a family of particle counters ranging from handheld portable particle counters to benchtop air quality units. Our particle counters are capable of communicating with most popular building automation systems.
