Electrical Stability Test to monitor a fluid’s emulsion stability and oil-wetting capability. This new model is simple to operate and can be used anywhere
Contact UsThe Fann Electrical Stability Tester, Model 23E is a portable instrument that measures the electrical stability (ES) of an oil-based drilling fluid. The EST conforms to the electrical stability test procedure that is described in API Recommended Practice for Field Testing Oil-based Drilling Fluids, API RP 13B-2. The EST includes the meter, electrode probe, 2 batteries, a power cord, 2 calibration standards, and a plastic carrying case.
The drilling fluid’s electrical stability is measured by applying a steadily increasing sinusoidal alternating voltage across a pair of parallel plate electrodes (probe). This probe is submerged in the oil-based drilling fluid. It is recommended that you record several measurements to establish a trend. These measurements will reflect an accurate condition of the drilling fluid and provide a basis for drilling fluid treatments.
