Beschreibung
Zusammenfassung:	A viscometer-densimeter for a down hole tool positionable in a well bore penetrating a subterranean formation is described. The formation contains at least one fluid therein. The down hole tool is adapted to convey at least a portion of the fluid to the viscometer-densimeter. The viscometer-densimeter comprises a sensor unit, and at least one magne t. The sensor unit is positionable within the down hole tool and comprises at least two spatially disposed connectors and a wire suspended in tension between the at least two connectors such that the wire is available for interaction with the fluid when the viscomete r- densimeter is positioned within the down hole tool and the down hole tool is positioned within the subterranean formation and receives the fluid from the subterranean formatio n. The connectors and the wire are constructed so as to provide a frequency oscillator.
