What type of detector is used for identifying Carbon Monoxide (CO)?

The correct answer is a Carbon Monoxide Detector, which is specifically designed to identify the presence of carbon monoxide in the environment. These detectors work by continuously monitoring the air for CO levels and alerting individuals when concentrations reach a potentially hazardous level. Carbon monoxide is a colorless, odorless gas produced by incomplete combustion of carbon-containing fuels, and exposure can lead to serious health issues, including fatal outcomes. Because of its unique properties and health risks, specialized detectors are essential for early detection and safety.

In contrast, detectors designed for other gases, such as nitrogen dioxide, hydrogen, or hydrogen sulfide, have different functionalities and target different chemicals. Therefore, they will not accurately monitor or detect carbon monoxide levels. This specificity of the carbon monoxide detector makes it the essential tool for monitoring CO in various environments, particularly residential and industrial settings.
