Estimating the term…
In a pair of electrodes where a potential difference is changed in accordance with acidity or basicity of oil, a reference electrode is made of cobalt or a cobalt alloy, and a sensitive electrode is made of tungsten or a tungsten alloy. The sensitive electrode is used in combination with the reference electrode. Accordingly, it is possible to provide a pair of electrodes for detecting the acidity or the basicity of the oil which use a novel electrode material not hazardous to the environment and at the same time, suited for use in a semiconductor fabrication technique.
A pair of electrodes for detecting acidity or basicity of oil, the pair of electrodes are constructed by
A reference electrode used in combination with a sensitive electrode, for a pair of electrodes where a potential difference is changed in accordance with acidity or basicity of oil, wherein the reference electrode is made cobalt or a cobalt alloy.
A sensitive electrode used in combination with a reference electrode, for a pair of electrodes where a potential difference is changed in accordance with acidity or basicity of oil, wherein:
A detecting device for detecting acidity or basicity of oil, the device comprising:
