Abstract
A fluid aspiration probe apparatus for automatic fluid testing equipment includes a pair of electrodes mounted on a distal probe tip. The electrodes are coupled to an impedance measurement apparatus via conductive pathways along the probe. The impedance measurements and probe tip height are monitored as the probe tip is lowered into a fluid sample. Boundaries between layers of fluid in the container are detected by recognizing sudden changes in the impedance measurements and heights of the boundaries are determined by tracking the position of probe tip when the sudden changes of impedance occur.
