Particle Counter

Particle counters measure airborne particle concentrations by size, giving you real-time data for cleanroom classification, filtration verification, indoor air quality investigations, and contamination troubleshooting. Use an optical particle counter like the TSI AeroTrak 9306 for multi-channel counts (0.3 to 10 µm) in controlled environments, or a TSI DustTrak DRX (8533 desktop, 8534 handheld) for simultaneous PM1, PM2.5, PM4, PM10, and Total PM mass concentration readings on jobsites and in buildings. For personal exposure monitoring, the TSI SidePak AM520 clips to a worker and logs breathing-zone dust, fume, and diesel particulate matter (DPM) levels over a full shift, with an intrinsically safe AM520i option for hazardous atmospheres. The TSI P-TRAK 8525 targets ultrafine particles (0.02 to 1 µm) to trace combustion sources and filter leaks that conventional monitors miss. Every kit ships with accessories, software, and documentation, and our team can help you select the right instrument and sampling plan for your environment.
