- Abstract
- The merits and demerits of various electrochemical sensors are discussed keeping in view their use for continuous monitoing of CO in hazardous areas of coal mines. The discussion shows that these sensors have least technical problems and have no interference with other gases and even with water vapor. These sensors consume power in micro range and so are intrinsically safe even if used in hazardous areas of coal mines. The response and reproducibility of operations are promising even if used continuously for days and months. The most reliable and simple sensors are either galvanic or those which operateon the fuel cell principle.
