STEAM QUALITY APPARATUS ABSTRACT A downhole steam sampler for collecting the liquid phase content of a steam flow, immediately prior to the latter being injected into a substrate surrounding a hole or well. A reservoir within the sampler separates and retains the liquid phase while permitting the vaporous phase to pass. Detent means cooperates with a pair of spaced apart flow control valves to permit said valves to be closed simultaneously when the steam sampling operation is completed. The detent means is actuated in response to withdrawal of the sampler from the well, an action which displaces an externally positioned sleeve.
