Final answer:
A gas analyzer measures gas concentrations using various technologies and is used for detailed analysis in labs or industry, while a gas monitor is aimed at safety in various environments, with alarms for hazardous levels.
Step-by-step explanation:
The difference between a gas analyzer and a gas monitor revolves around their functionality and applications. A gas analyzer is a device that precisely measures the concentration of gases, and they can employ a variety of technologies—such as ionization gauges, electrochemical cells, and infrared spectroscopy—to identify and quantify gas components. In contrast, a gas monitor is typically used for safety and health monitoring in various environments, often providing real-time concentration levels and featuring alarms that can be set to go off when certain thresholds are exceeded.
Gas analyzers are commonly used in industrial applications, research laboratories, and environmental monitoring, where detailed information about gas composition and concentration is crucial. They can measure a wide range of gases and can use complex techniques such as gas chromatography to separate and identify individual chemicals. Gas monitors, on the other hand, are often used in confined spaces, commercial or residential buildings, or by personal users to detect hazardous gases like carbon monoxide or to monitor oxygen levels, as indicated by devices like pulse oximeters that measure oxygen in the blood, and are important for determining a person's metabolic rate.
