A system includes a fluid conduit, a fluid chamber in communication with the fluid conduit, a rheology sensor in communication with the fluid chamber, and an electric temperature controller in communication with the fluid chamber. The fluid chamber is cooled in response to a first control signal from the electric temperature controller.

A system includes a fluid conduit, a fluid chamber in communication with the fluid conduit, a rheology sensor in communication with the fluid chamber, and an electric temperature controller in communication with the fluid chamber. The fluid chamber is cooled or heated in response to a first control signal from the electric temperature controller.

A bob for a viscometer in a portable rheology unit is provided. The bob may include a bob portion having a cylindrical portion and a first end portion, the cylindrical portion defining a first end of the bob. The bob may also include a plastic portion interfacing with an interior surface of the first end portion, wherein the plastic portion includes a conical area extending from a conical area first end to a conical area second end, and the conical second end is connected to an interior surface of the cylindrical portion. The bob may also include a sleeve portion connected to the plastic portion and a bob second end portion connected to the sleeve portion.

An electrical stability testing device includes a cup configured to receive a fluid sample. The testing device also includes a pair of electrodes positioned at least partially within the cup. The electrodes are spaced apart from one another by a predetermined gap. The electrodes are configured to have the fluid sample positioned within the predetermined gap while performing an ES test on the fluid sample in the cup. The testing device also includes a wiper positioned at least partially within the cup. The wiper is configured to pass between the electrodes after the ES test has concluded. A width of the wiper is greater than the predetermined gap between the electrodes. The wiper is configured to deform as the wiper passes through the predetermined gap such that the width becomes substantially equal to the predetermined gap and sides of the wiper contact ends of the electrodes to clean the electrodes.
