1.Overview
The model HSHD-1702 Electrical Stability Tester (EST) is a specialized instrument mainly used to test the relative stability of water in oil emulsions. It tests the stability range of water in oil emulsion drilling fluids and predicts the resistance and time stability of electrolyte impurities in these systems from the measurement of relative emulsion stability. This instrument can also evaluate oil-based drilling fluids, oil-based debonding agents, cement, and fracture water. Therefore, it can be widely applied in departments such as petroleum, geology and mining, drilling teams, and laboratories.
