The GrayWolf PC-3500 is a rugged, handheld 6-channel laser particle meter that simultaneously measures airborne particles at six size ranges and reports both count and calculated mass concentrations (like PM2.5 and PM10). Its bright color touchscreen, internal pump and onboard data logging make it ideal for indoor air quality surveys, environmental monitoring, contamination tracking and compliance testing — whether used stand-alone or connected to GrayWolf instruments and software.
