  • Patent number: 4217194
    Abstract: A probe having a measuring device for polarographic, potentiometric, ther and like measurements has a high-resistance transducer which is provided with leads. A body of insulating material is arranged about the transducer and a metal-containing body is arranged about the insulating material. The metal-containing body includes a metal layer which is essentially free of pores and essentially impervious to the diffusion of liquid therethrough and which thus seals the insulating material against contamination by foreign matter. A metal layer which is essentially free of pores and essentially impervious to the diffusion of liquid therethrough may be formed by sputtering the metal onto a substrate using a high-frequency field at an output of 10 to 40 watts per square centimeter of target surface, the sputtering operation being carried out for a period of 5 to 10 minutes in an Ar atmosphere having a pressure of 8 .times.10.sup.-4 torr.
