Monitors that detect specific toxic gases and flammable gases are:

• A. UEL detectors.
• B. Calibrated field testers.
• C. Multi-gas monitors.
• D. Indirect readings.

Answer: (C)

Monitors that detect specific toxic gases and flammable gases are multi-gas monitors. These devices are built to sense several gas types at once, using a mix of sensors: electrochemical sensors target toxic gases like carbon monoxide or hydrogen sulfide, delivering ppm readings; catalytic (pellistor) sensors detect combustible gases and provide an LEL (lower explosive limit) reading. Because they combine multiple sensor types in one portable unit, they give real-time, continuous monitoring in hazardous environments and alert you to dangerous concentrations across several hazards simultaneously. The alternative like UEL detectors focus on the upper explosive limit of a gas mixture and don’t identify which gases are present or their concentrations. Calibrated field testers are for discrete sampling and calibration checks rather than continuous multi-gas monitoring. Indirect readings don’t provide direct gas concentration measurements. So, the device that monitors for both specific toxic gases and flammable gases is a multi-gas monitor.
