balance de Westphal

CONT: Destinée à la mesure des densités, la balance de Westphal est constituée par une potence à tube vertical et par un bras supportant sur un couteau un fléau à bras inégaux.

CONT: Westphal balance - Sauter. Measures the specific gravity/density of solids and liquids: the plummet (weight) is immersed in the liquid of unknown density; alternatively an unknown density is immersed in liquid of known density; the loss of weight is measured on the balance.
CONT: A Mohr-Westphal density balance. This instrument was first described in 1832 by the German chemist Carl Friedrich Mohr. It is a balance with two arms, where the equilibrium is reached by adding weight on a tray. This type of instrument was modified by G. Westphal who replaced the tray with an adjustable counterweight.

CONT: La balanza de Mohr-Westphal es una balanza de brazos desiguales que se utiliza para la determinación de densidades de líquidos. En esencia, consta de un armazón o montura ajustable en altura sobre el que se apoya una varilla segmentada en dos brazos.
