p H Measurements with a Glass Electrode Withstanding 1500 kg/cm2 Hydrostatic Pressure
A glass electrode can be made to withstand high hydrostatic pressure, up to 1500 kg/cm2, by separating the inside fluid from the outside one with a layer of silicone oil acting as a liquid piston, enabling the inside and outside pressure to compensate continuously. Such a glass electrode, with two A...
