1. Product Introduction of Electrical Stability Tester (EST) Model DWY-2A
Electrical stability tester is a portable instrument for measuring the electrical stability (ES) of oil-based drilling fluid. The electric stability of drilling fluid is related to its emulsion stability and wettability. The tester complies with the electrical stability test procedure described in API rp13b-2 Recommended Practice for field testing of oil-based drilling fluid.
The instrument is mainly composed of an instrument box, test body, electrode, power adapter and glass beaker.
Electric stability tester is a sine wave instrument, which is used to measure the relative electric strength of drilling fluid with continuous oil phase in conventional field and laboratory. It is accurate, simple and portable. The influence of the chemical composition and shear history of drilling fluid on the absolute value of ES is very complex. Therefore, it is not advisable to explain the wet state of drilling fluid according to the single measurement of ES. When deciding the treatment plan of drilling fluid, it can only be based on the change trend of ES.

4. Product working principle of Electrical Stability Tester (EST) Model DWY-2A
The measurement of electrical stability (ES) is to apply a sinusoidal electrical signal with gradually rising voltage to a pair of parallel plate electrodes immersed in drilling fluid. The resulting current is very weak until it reaches a critical voltage, after which the current intensity rises sharply. This critical voltage, known as the ES value of the oil-based drilling fluid, is defined as the peak voltage measured when the current intensity reaches 61ua, in volts.
