Gas sensors
Controlled potential electrolysis sensor
From the mid-1960s, controlled potential electrolysis type sensors have attracted much attention as a means for sensing and measuring air pollutants such as sulphur dioxide and nitrogen oxide right at the source where they are generated and they are increasingly being used in such contents. In the latter half of the 1970s, they came to be more widely accepted as carbon monoxide or hydrogen sulphide measuring instruments alongside other combustion type or galvanic sensors, not only for flue gas monitoring or occupational hygiene and safety applications.
