Date Dec. 11, 1997A portable sampling system (10) and method for use with a cargo tank's vapor control valve (12) or other entry device to enable an operator to extract and bottle a product sample in place without transfer of a collected sample to another container or through an open atmosphere. A built-in sampling valve (34) and sample bottle fill attachment (44) are coupled with a vapor return hose assembly (58) to a hand held gauging apparatus for collection of the product sample free of human contact and so as to eliminate vapor release to the atmosphere and to protect an end user from possible exposure to toxic vapors. A tape reel mechanism (14) is connected with a sampling barrel (32) through which a product sampling tube (33) attached to a tape reel (66) in tape reel housing (16) and is lowered into the tank (12a) to obtain the product sample. A vapor control valve (12) is coupled between the sampling barrel and the tank.
