Which gases can the MX6 detect, and what are their measurement ranges?

The MX6 is a versatile multi-gas detector designed to monitor various hazardous gases, making option C the correct choice due to the inclusion of Carbon Monoxide, Methane, and Oxygen, all of which are critical to assess in environments such as mines.

Carbon Monoxide detection is essential because even low levels of this gas (up to 10,000 ppm) can pose severe health risks due to its toxicity and ability to interfere with oxygen transport in the bloodstream. Methane, being a flammable gas, needs to be monitored especially in mines to prevent the risk of explosions, and the measurement range of 0 - 5% vol is appropriate for this application.

Oxygen levels are vital for ensuring safe environments for workers, and the capacity to measure between 0 - 30% volume allows for comprehensive monitoring, as oxygen levels below 19.5% can indicate an asphyxiation hazard.

The other choices present gases that, while important, either do not cover a complete suite of critical monitoring or are limited in range for safety assessments in mine environments. The gases listed in option C are particularly relevant for the mining industry where air quality and the presence of toxic or explosive gases are constant concerns. Thus, the selection of Carbon
