Air Particle Counter – Portable / Handheld


Air-borne particle counters are used in the monitoring and control of particles in cleanrooms, gloveboxes, laminar clean hoods, coating / plating areas, sensitive production areas, process tools, and filtration media testing.  

RION particle counters can measure size and count of particles in a wide range of applications to determine classification, certification, and compliance of ISO 14644-1, Fed-Std-209E, EU-GMP, FDA, and Pharmacopeia regulations. 

The handheld and portable models maximize flexibility and cost-effectiveness, giving you the capabilities you need when and where you need it. These instruments’ mobility also allow identification of particle sources to provide actionable information for immediate contamination control and management.  

RION offers ISO 21501-4 (JIS B 9921) and FDA 21CFR11 compliant sensors and software to help you monitor and manage your air-borne particles.  Please contact our representatives to see how RION and MGN can support your needs.
