dg_verewa

As part of the Durag group based in Germany, Verewa manufactures particulate samplers for the ambient air quality market. The samplers operate on a beta-gauge mass determination principle.  By selecting the appropriate sample probe head, a basic TSP sampler can easily be converted to a PM2.5 or PM10 sampler.  In such cases use is made of USEPA-certified particle separation heads.

 

 

airmetrics

Airmetrics is dedicated to providing practical and innovative solutions to ambient air monitoring problems. They manufacture the MiniVol™ TAS and offer a complimentary line of calibration orifices, filter cassettes, mailers and Tedlar bags.

MiniVol samplers are battery-driven and particulates are collected on 47 mm filters.  Mass determination is done manually using gravimetric methods.  By selecting a suitable sampling head, the sampler can serve either as a PM2.5, PM10 or TSP sampler.  Their low costs make MiniVol samplers the ideal screening tool on which the need for long-term particulate monitoring decisions can be based.
