The electrical stability tester is a portable instrument for measuring the electrical stability (ES) of oil-based drilling fluid. The instrument is mainly composed of test unit, electrode probe, power cord, 4pcs battery. It is have the characteristics of high measurement accuracy, small repetition error, safe and reliable, easy to operate, accurate measure data, has been widely used in oil field, research institutes, laboratory and other departments. The measurement of electrical stability (ES) is to apply a sinusoidal telecomunication signal with gradually rising voltage to a pair of parallel plate electrodes immersed in drilling fluid. The generated current is very weak until it reaches a critical voltage, and then the current intensity rises sharply. This critical voltage is called the ES value of the oil-based drilling fluid and is defined as the peak voltage measured at the current intensity of 61ua, unit is volts.
