Standardy hustoty

Hustotní standardy lze použít jako kalibrační standardy pro měření hustoty pomocí pyknometrických, vibračních nebo hustoměrných metod. Tyto standardy jsou připraveny gravimetricky (rozpouštědlo a rozpuštěná látka) za použití závaží sledovatelných dle OIML. Hustota standardů je stanovena pomocí plně kalibrovaných referenčních pyknometrů. Jsou vysoce přesné a kompatibilní s jakoukoli značkou či typem zařízení pro měření hustoty. Standardy jsou dodávány ve vysoce kvalitní, nerozebíratelné jantarové skleněné lahvi.
