A probe for determining at least one rheological property of a fluid contained in a recipient, the probe comprising: an inner member holding a load cell; an outer member adapted to be placed in contact with said fluid, said outer member being submittable to a pressure applied by the fluid and being adapted to transfer a force resulting from said pressure to the inner member and thereby deform the load cell, the load cell thence providing an indication of a value of said deformation; a base connected to the inner member, said load cell being prevented from being in contact with said fluid by said outer member and said base; characterized in that it comprises: at least one position sensor to provide an indication of a position of the probe; an electronic module in electronic communication with the load cell and the at least one position sensor, the electronic module having a processing unit to determine a speed value of the probe based on said indication of a position and to determine the at least one rheological property of the fluid based on the speed value of the probe and the value of the deformation obtained from the load cell; wherein said at least one rheological property of the fluid is determined when the probe is displaced in the fluid in the recipient and without having to remove a sample of fluid from the recipient to analyze it externally. an inner member holding a load cell; an outer member adapted to be placed in contact with said fluid, said outer member being submittable to a pressure applied by the fluid and being adapted to transfer a force resulting from said pressure to the inner member and thereby deform the load cell, the load cell thence providing an indication of a value of said deformation; a base connected to the inner member, said load cell being prevented from being in contact with said fluid by said outer member and said base; characterized in that it comprises: at least one position sensor to provide an indication of a position of the probe; an electronic module in electronic communication with the load cell and the at least one position sensor, the electronic module having a processing unit to determine a speed value of the probe based on said indication of a position and to determine the at least one rheological property of the fluid based on the speed value of the probe and the value of the deformation obtained from the load cell; wherein said at least one rheological property of the fluid is determined when the probe is displaced in the fluid in the recipient and without having to remove a sample of fluid from the recipient to analyze it externally. at least one position sensor to provide an indication of a position of the probe; an electronic module in electronic communication with the load cell and the at least one position sensor, the electronic module having a processing unit to determine a speed value of the probe based on said indication of a position and to determine the at least one rheological property of the fluid based on the speed value of the probe and the value of the deformation obtained from the load cell; wherein said at least one rheological property of the fluid is determined when the probe is displaced in the fluid in the recipient and without having to remove a sample of fluid from the recipient to analyze it externally.
