Photoluminescent oxygen probe tack

摘要

A photoluminescent oxygen probe (10) comprising a tack (20) with a layer of a pressure-sensitive adhesive (40) and an oxygen-sensitive photoluminescent element (30) on the underside of the head. The probe is effective for sensing oxygen concentration within an enclosed space by puncturing the container defining the enclosed space with the probe's shank (22) and adhering the underside of the probe's head to the container so as to sealingly surround the puncture, thereby placing the oxygen-sensitive photoluminescent dye on the underside of the probe's head into sensible communication with the enclosed space through the puncture hole.
