  • The particle counter is an essential tool in the HVAC/IAQ professional’s toolbox. From filter testing to basic IAQ investigations, the particle counter equips the user with valuable data concerning the concentration and source of particulates in the tested environment. Airborne particles can settle onto sensitive surfaces or carry allergens and bacteria into Fluke 983 Particle Counter.

    • Selectable sample time, count data, programmable delay 
    • Set sample size to cubic feet or liters, set temperature measurements to ˚C or ˚F 
    • Data displayed in totalize or concentration modes 
    • Logged samples include date, time, particle counts, sample volume, temperature and relative humidity.
