Densitetsstandarder

Densitetsstandarder kan anvendes som kalibreringsstandarder til densitetsmålinger ved hjælp af pyknometriske, vibrationsbaserede eller hydrometerteknikker. Disse standarder fremstilles gravimetrisk (opløsningsmiddel og opløst stof) med OIML-sporbart vægtudstyr. Densiteten bestemmes ved hjælp af fuldt kalibrerede referencenpyknometre. Densitetsstandarderne er meget præcise og kan bruges med alle mærker og typer af densitetsmålere. Standarderne leveres i høj kvalitet, uåbnelig ravfarvet glasflaske.
