| 摘要 |
A sensing electrode consisting of electrically nonconductive underlay (1), made up of polymeric matter, with pH sensitive antimony layer (2) deposited onto, which is connected by means of a secondary conductor (3) with a measurement device (6) in a place, which is out of reach of the system, of which pH is measured. A pH sensitive antimony layer (2) of thickness from 1 micrometer to several millimeters is deposited onto a nonconductive underlay (1) by a method where a metal is evaporated under a vacuum - sputtering, magnetron sputtering, radiofrequency sputtering, diode plasma sputtering, cathodic arc evaporation, ion plating, ionization-assisted evaporation, ion implantation or laser alloying. A sensing electrode is, with benefit, a part of a measurement system, consisting of more sensing electrodes, where each of them is, by means of secondary conductor (3), connected with a measuring device (6) to which one reference electrode (5) is connected to. |
