The Electrical Stability (ES) of an oil-based drilling fluid is directly related to its emulsion stability and oil wetting ability. The Emulsion Stability Meter determines ES by applying a precision voltage-ramped sinusoidal signal across a pair of parallel flat plate electrodes that are immersed in the fluid. The resulting current remains low until a threshold voltage (61 ± 5 µA) is reached. Then the current rises very rapidly. The point at which the fluid becomes conductive is the peak volts measured when the current reaches the 61 µA point.
The Advanced Emulsion Stability Meter combines the reliable technology of the Standard ES Meter with a set of advanced features that enable you to go beyond standard testing. It can accept power from an AC source, a DC source, 9 volt batteries (4), or a computer USB port. The PC software stored on the meter provides advanced control and reporting capabilities. And the probe connection has been improved to prevent test fluid from damaging the internal components.
