Gas Vapor Dedicated Points are now used around the world for monitoring remediation of hydrocarbon spills, tank & pipe leakage, landfills, & at hazardous waste sites. Soil gas monitoring with the Gas Vapor Dedicated Point is easily accomplished. The unique design of the dedicated stainless steel vapor point, with a Teflon umbrella & optional screen to prevent soil from clogging the vapor inlet holes, or for groundwater sampling, ensures a representative sample time after time. Teflon tubing is used to transfer the sample to the surface. The Gas Vapor Probe is normally supplied as a complete system kit form with all the items needed to efficiently install the dedicated points in most penetrable soils.
