Carbon Monoxide Sensor Cross-Sensitivities Alcohols, VOCs ...

among electrochemical sensors. Cross-sensitivities are limited as much as possible by MSA sensor design and filters; however, some key interactions still occur. CO sensors do have some inherent characteristics in terms of saturation, cross-sensitivity and cross-interference that may affect sensor performance. A typical electrochemical gas sensor contains three electrodes: the sensing electrode ...
