HazardEx - Understanding gas sensor lifespan

Electrochemical sensor life prediction is a very inexact science - operational life-spans are totally influenced by the factors described in this article and thus are unique to each application. In practice,sensors are either replaced at a fixed time period based on manufacturers’recommendations or previous data ( every 2 or 3 years), or when they respond inadequately to test gas. In the ...

Carbon monoxide detector - Wikipedia

The electrochemical detector uses the principle of a fuel cell to generate an electrical current when the gas to be detected undergoes a chemical reaction. The generated current is precisely related to the amount of carbon monoxide in the immediate environment close to the sensor. Essentially, the electrochemical cell consists of a container, two electrodes, connection wires and an electrolyte ...

Electrochemical Sensors: Life Expectancy | InstruMetriX ...

2008-07-07· For toxic sensors (CO, NO, NO2, SO2 etc.) two years lifetime is common. Experience shows that one can expect these electrochemical sensors to last about three years if the instruments are maintained properly, and the concentrations the sensors are exposed to are within the range regulations in most developed countries require. There are ...

Why is hydrogen such a big issue for CO sensors? | GfG ...

How electrochemical CO sensors detect gas. Gas that enters the sensor undergoes an electrochemical reaction that causes a change in the electrical output of the sensor. The difference in the electrical output is proportional to the amount of gas present. Gas enters the sensor through an external diffusion barrier that is porous to gas but nonporous to liquid. An internal organic vapor filter ...
