{"title":"Particle Counters","description":"\u003cp\u003eA particle counter counts airborne particles by size; a particle monitor reports their mass. The Met One \u003ca href=\"\/en-us\/products\/particle-counters\"\u003eAerocet 532\u003c\/a\u003e does both in one handheld unit: counts in eight channels from 0.3 to 10 µm, and PM1, PM2.5, PM4, PM7, PM10 and total suspended particulate in µg\/m³, computed in as little as 60 seconds. It suits indoor air quality surveys, dust source tracing and occupational screening. Mass is converted from counts, so user K-factors (0.1 to 20.0) tune it to your dust against a reference or gravimetric method. It is not a cleanroom classifier: ISO 14644-1 sets its classes at sizes from 0.1 to 5 µm, and the records do not claim it.
