Most instruments for measuring fluid density are not absolute instrumentsthey must be calibrated with one or more fluids of known density. The selection of appropriate calibration fluids is vital to achieving low uncertainty in a measurement. Also important is establishing the traceability of the calibration fluids (and thus the measurement) to established standards. This chapter discusses the concept of traceability and outlines the types and sources of available calibration fluids.
