Particulate Meters, Monitors, Instruments

For IAQ, PM2.5, PM10 Measurement, Data-Logging (and more)

GrayWolf’s 6-channel handheld, desktop and wall-mount air particulate meters, PM2.5 and PM10 monitors, and particle counters all interface with GrayWolf DirectSense®, AdvancedSense® Pro, and WolfSense® LAP enabled instrumentation. With the exception of the PM-601 particulate concentration meters, they also can connect with WolfSense Mobile on Android and iOS devices. Use these particle meters as stand-alone instruments, and/or interface them to display and log particulates directly on a GrayWolf instrument, Mobile PC, smartphone, and/or to the cloud, all simultaneously with one or more GrayWolf multi-sensor probes.
