This HiVol 3000 PUF sampler offers dependable sampling of natural compounds on a Poly-urethane foam. This device is specifically constructed to sample a vast array of organic compounds, and keep them in a clean environment. It combines this sampling with basic meteorological parameters, and can be used for fenceline sampling. Ecotech has also developed an XAD sampler applicable for measuring wider range of compounds. The device's nominal volumetric flow range is at a nominal 10-20m3/hr.
