A measuring device is disclosed that includes a shaft, a display and/or control unit pivotally supported on an upper end of the shaft, and at least one sensor element disposed in the shaft and operatively connected with the display/control unit. The shaft has at least one foldable shaft section. The device can be operated with one hand and allows flow measurements in channels of varying depth.

Measuring device

A waterproof protective device for holding an apparatus having an interaction field is formed from a dimensionally stable protective housing having a lower housing part and an upper housing part. The lower housing part and the upper housing part are releasably hingedly connected with one another and an inside contour of the protective housing is adapted and constructed to closely receive the apparatus with approximately zero play. The protective housing is provided with a transparent, elastically flexible operating area of reduced wall thickness to enable an interaction field to be viewed and manipulated. The operating area may be integral with the rest of the protective housing and may be sufficiently elastically deformable so that pushbuttons on the apparatus may be operated by finger pressure through the protective device under the operating area. A seal is provided between the upper housing part and the lower housing part, and is formed of a mating circumferential groove and rim, one or both of which may be provided with lips. The watertight protective device may also include additional features such as recesses on a side facing away from operating area to enable the protective device to be fastened to a matching mount or a stand fastened by a hinge to the protective housing. At least one reinforcing strip may be provided on the protective housing and formed from the same material as the protective housing. A watertight plug aperture may be formed in the protective housing. To facilitate removal of the apparatus from the protective housing, an area of reduced wall thickness and adjacent pusher may be formed on an area opposite a removal opening, so that an user can partially push the apparatus out of the lower housing part.
