System and method for cleaning electrical stability probe

An electrical stability (ES) testing device, comprising:

• a cup configured to receive a fluid sample;
• a pair of electrodes positioned at least partially within the cup, wherein the electrodes are spaced apart from one another by a predetermined gap, and wherein 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;
• and
• a port positioned at least partially within the cup, wherein the port is configured to have a cleaning fluid flow therethrough after the ES test has concluded, and wherein the cleaning fluid flows toward the electrodes, through the predetermined gap, or both at a velocity that is greater than or equal to about 1 m/s to clean the electrodes, and, wherein a distance between ends of the electrodes and the port is less than about 1 CM.

A method for performing an electrical stability (ES) test, the method comprising:

• increasing a voltage applied to a pair of electrodes until an electrical current between the electrodes reaches a predetermined threshold, wherein the electrodes are submerged within a fluid sample within a cup, and wherein the electrodes are spaced apart from one another by a predetermined gap;
• decreasing the voltage after the electrical current reaches the predetermined threshold;
• and
• causing a wiper in the cup to pass through the predetermined gap and contact the electrodes after the voltage is decreased, wherein a width of the wiper is greater than the predetermined gap, and wherein 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.
