A mobile sampler 10 for use in acquiring samples of terrestial atmospheric gasses from a free body of such gasses. The device is chracterized by a plurality of tubular bodies 12 adapted to be mounted in side-by-side relation on a motorized highway vehicle V in mutual parallelism with the axis of the normal path of travel for the vehicle; each of the bodies is of a cylindrical configuration and has an axial opening disposed at each of its opposite ends whereby a linear flow path is defined therethrough, a pair of pivotally supported, spring-biased sealing caps 14A and 14B mounted adjacent the ends of the body and continuously urged into hermetic sealing relationship therewith, a restraint for securing the caps against spring-urged pivotal displacement, including a separable, normally tensioned line 52 interconnecting the caps and an operable release mechanism for simultaneously releasing the caps for spring-urged displacement, including a hot wire cutter 54 for separating said line, whereby samples of air are trapped in the body as the caps are spring-driven to assume an hermetically sealed relation with the openings defined in each of the opposite ends of the body.
