DUSTTRAK DRX Aerosol Monitor 8533 and 8534

The DUSTTRAK™ Aerosol Monitor is a portable,battery-operated laser photometer with real-time mass concentrationreadout and data logging capability. The monitor provides reliableexposure assessment by measuring particle concentrationscorresponding to respirable size, PM10, PM2.5 or PM1.0 sizefractions.

Suitable for clean office settings as well as harsh industrialworkplaces and outdoor applications, the aerosol monitor detectspotential problems with airborne contaminants such as dust, smoke,fumes and mists. The DUSTTRAK aerosol monitor is easy to use. Youcan perform quick spot checks or program the advanced logging modesfor long-term unattended sampling.
