Summary:The present invention comprises an apparatus for placement and retrieval of gauges employed to measure temperature, pressure and other parameters in a well bore. The apparatus comprises a gauge receptacle means incorporated in a pipe string including a substantially tubular outer housing having a substantially tubular inner housing substantially coaxially therein, the inner housing being supported in the outer housing by a plurality of support rings having longitudinally extending apertures therethrough. The inner housing has a landing nipple profile cut therein, whereby a locking mandrel having a gauge holder secured thereto may be run into the pipe string on a wireline, and locked into the inner housing after which the wireline may be retracted. The locking mandrel may also be subsequently unlocked and retrieved with the gauge holder by wireline.
