The Gas Vapor Probe System is the finest system available today for environmental assessment and monitoring. It is available as a series of kits from a Basic Kit without a drill to a Heavy Duty Kit that also includes AMS Flighted Augers. Used for collecting samples of soil gas at shallow depths. Tips are offered in a dedicated tip or a retract-a-tip, which is removable. The AMS Gas Vapor Probe has been designed specifically for placement of devices used to recover soil gas samples. The GVP kit may also be used for collection of soil and groundwater samples when used with accessory screens that are sold separately.
