Abstract: This article examines electrochemical carbon monoxide (CO) sensors used as mobile devices by rescue and firefighting units in Poland. The conducted research indicates that the presence of chlorine (Cl 2 ), ammonia (NH 3 ), hydrogen sulfide (H 2 S), hydrogen chloride (HCl), hydrogen cyanide (HCN), nitrogen (IV) oxide (NO 2 ), and sulfur (IV) oxide (SO 2 ) in the atmosphere does not affect the functioning of the electrochemical CO sensor. In the case of this sensor, there was a significant cross effect in relation to hydrogen (H 2 ). It was found that the time and manner of using the sensor affects the behavior in relation to H 2 . Such a relationship was not recorded for CO. Measurements in a mixture of CO and H 2 confirm the effect of hydrogen on the changes taking place inside the sensor. Independently of the ratio of H 2 to CO, readings of CO were flawed. All analyses showed a significant difference between the electrochemical CO sensor readings and the expected values. Only in experiments with a 1:3 mixture of CO and H 2 was the relative error less than 15%. The relative error in the analyzed concentration range for a sensor with an additional compensation electrode ranged from 7% to 38%; for a sensor without this electrode, it ranged from 23% to 55%. It was ascertained that in the cases of measurements for tests carried out at higher concentrations of H 2 in relation to CO, a sensor with an additional electrode is significantly better (more accurate) than a sensor without such an electrode. Differences at the significance level p = 0.01 for measurements made in the CO:H 2 mixture at a ratio of 1:3 were ascertained.
