MET ONE Instruments’ HHPC 6+ handheld particle counter is used to classify an ISO Class 5 clean room and the related ISO Class 7 gowning room.

Now available and ready for measurement. Portable Particle Counters engineered for users to make their job easy. Whether working in pharmaceutical manufacturing, semiconductor and electronics ...

It is recommended to use a particle counter with 0.5 µm sensitivity for pharmaceutical manufacturing ISO class definition. Pharmaceutical cleanrooms typically operate at Class 5 ...

Today’s standards define airborne particle monitoring in units of particles per cubic meter (particles/m 3).. These standards tend to require sampling an entire cubic meter (1 m 3) to establish an ...

Examples of Particle Class Morphology. LNF Compared to Optical Particle Counters. LNF perform essentially the same function as traditional laser particle counters and analytical ferrography. However, ...

Sample at higher flow rates decreases particle loss. A follow-up study used 100 LPM particle counters, various 3/4-inch OD sample tubing lengths, and 5.0 μm PSLs.
