Carbon Monoxide (CO) Poisoning in Your Home - EH ...

Mar 22, 2021· Carbon monoxide (CO) is an odorless, colorless gas formed by the incomplete combustion of fuels. When people are exposed to CO gas, the CO molecules will displace the oxygen in their bodies and lead to poisoning. The Problem with CO. Since CO has no odor, color or taste, it cannot be detected by our senses.

The challenges with electrochemical NO2 sensors in outdoor ...

Jul 23, 2018· Interfering gases and cross-sensitivity. In a perfect world, an electrochemical sensor would only respond to the gas it is targeted to monitor. A nitrogen dioxide (NO 2) sensor would only detect NO 2 and a carbon monoxide (CO) sensor would only detect CO and so on. While electrochemical sensors are designed to be as specific as possible, most will respond in some manner to gasses …

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%.
