measurement of pH-solutions. SUBSTANCE: sensitive element in metal-oxide pH-electrode is ion-sensitive outer surface of case manufactured of metal in the form of sleeve with metal rod- electric conductor placed in its internal space, in center along axial line, electrically connected to bottom base of sleeve with use of another metal or ion-conductive solution and insulated from its side internal surface. EFFECT: independence of potential of pH- electrode from agitation of liquid, stability in time, resistance to strong oxidizing agents, mechanical strength. 2 cl, 4 dwg |
