ULTRA Passive Samplers

The ULTRA Passive Samplers from SKC are the creative evolution of indoor and ambient air sampling. The patented* ULTRA samples by diffusion and provides low ppb to ppt detection of compounds, including semi-volatile organic compounds (SVOCs). Operation is as easy as sliding the cover open to start sampling and closing it to stop sampling.
