Emulsion Stability Tester

Emulsion Stability Tester

The Electrical Stability (ES) of an oil-based drilling fluid is a property related to its emulsion stability and oil wetting ability. The Emulsion Stability Tester determines ES by applying a precision voltage-ramped sinusoidal signal across a pair of parallel flat plate electrodes that are immersed in the fluid.

Features of Emulsion Stability Tester

• API recommended sinewave circuitry
• Symmetry of the sinusoidal signal inhibits the buildup of solids on the electrode faces and enhances reproducibility.
• Push button automatic voltage ramping at a fixed ramp rate
• Includes meter, probe electrode, calibration standards, and four 9-volt alkaline batteries
