The improvement of modern oscillation-type density meters requires density reference liquids with low uncertainty. The new apparatus for the hydrostatic measurement of density at PTB was improved to reach measurement uncertainties smaller than 0.005 kg m−3. Thus, it is now possible to deliver density reference liquids with an uncertainty of 0.01 kg m−3.
