Abstract
A densitometer is described which is equipped with an extendable and retractable measuring head driven by an electric motor. In the retracted rest position, a measuring diaphragm is visible to the user and the instrument may be positioned. In the extended working position the measuring head covers the measuring diaphragm. By means of the electric drive of the measuring head, the risk of erroneous positioning is avoided.
