What gas is primarily detected with a Multi-gas Detector besides Carbon Monoxide?

The primary gas that is commonly detected with a Multi-gas Detector, alongside Carbon Monoxide, is Hydrogen Sulfide (H2S). This gas is a significant concern in many industrial and agricultural settings, particularly where organic materials are decomposing or in areas such as oil and gas operations. H2S is highly toxic, with a characteristic rotten-egg smell at low concentrations, making its detection crucial for ensuring the safety and health of workers.

Multi-gas detectors are designed to monitor various hazardous gases in the environment, and while Nitrogen Dioxide, Ammonia, and Methane can also be detected, they are typically not as prominent as H2S in the contexts that most multi-gas detectors are used. Hydrogen Sulfide is particularly notable for its rapid onset of health effects, emphasizing the importance of its immediate detection to prevent potential poisoning or accidents in confined spaces or areas where it may accumulate. Thus, the focus on H2S as a key gas underscores its critical health and safety implications in various work environments.
