Galvanic-type electrochemical sensor for determining the ...

Jul 01, 2003· These sensors, however, are characterized by low speed of response and selectivity, insufficient accuracy within the hydrohalogen MPC range. For these reasons, amperometric-type electrochemical sensors are supposed to be preferably used. These sensors produce current directly proportional to the concentration of the component under determination.

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

The reason that CO sensors are potentially susceptible to hydrogen (H2) interference is the reaction that is used to detect gas. Hydrogen is actually part of the detection reaction. The relative response to hydrogen depends on the brand and model of sensor. Some commonly used CO sensors show a relative response to hydrogen as high as 60%.
