AMS dedicated gas vapor tips are used for detecting hydrocarbon spills, underground storage tank and pipe leaks, landfill contamination and hazardous waste sites. Soil gas monitoring with the AMS dedicated gas vapor tip is easily accomplished using an available AMS gas vapor probe kit. The unique design and umbrella ensure an easy passage for gas entering the collection system. The umbrella assists in keeping the tip vapor inlets free of soil. The option screen may be used, particularly in fine-grained soils or when sampling water.
