Monitor Airborne Particles In Controlled Environments

Ensure Operations Compliance & Safety

Cleanroom environments require that strict levels of cleanliness, temperature & moisture are maintained to ensure contamination free environments and increase yield. Various ISO cleanroom classes define the particles per cubic meter allowed.

Clean Room Particle Counters Guide medical factory and production indoor with BT-620

Design of a cleanroom is based on process requirements, room volume, classification (particles per volume), and the type of filtration required. Validation testing is used to establish periodic or continuous monitoring points. Our bench top BT-610 and BT-620 also provide a printed record and are ideal for ISO 14644-1:2015 Class 3 thru 9 cleanroom applications.

All models can meet the calibration requirements of ISO 21501-4 and meet the requirements for the manufacture of sterile medicinal products per EU GMP Annex I (EMEA) Grades A through D.

When monitoring is required in auxiliary areas, choose one of our portable units such as the GT-521S and GT-526S. These offer additional size selections and large data memories.

Hospitals, surgery centers, clinics, and medical laboratories monitor their air filtration systems for microorganisms such as bacteria or fungus particles. The GT-324 is well suited for such medical indoor air monitoring where HVAC and Filter Performance follow ISO16890 and ASHRAE 52.2 standards.
