Abstract
A calibration tool and method of using the tool to calibrate a fiber optic needle oxygen sensor. The tool includes at least a vial sealingly covered by a septa and containing a supply of particulate oxygen getter within the chamber of the vial. The vial has an open top and is constructed from an oxygen impermeable material. The septa is resealing, needle-penetrable and oxygen impermeable. The supply of particulate oxygen getter is retained within an oxygen permeable sachet.
