What does an air sampling detector measure?

An air sampling detector is specifically designed to measure the concentration of specific gases or combustion products in the atmosphere. These instruments play a crucial role in fire protection and hazardous materials management, as they help firefighters and safety personnel identify harmful components in the air. For example, in a fire situation, the detector can sense toxic gases like carbon monoxide or volatile organic compounds, allowing for a more informed response to the emergency. By measuring these concentrations, responders can assess the situation and take appropriate actions to ensure safety and effective mitigation of hazards.

The other options do not align with the primary function of an air sampling detector. While ambient temperature, water vapor, and sound levels may be relevant in specific contexts, they do not pertain to the core purpose of these devices, which is focused on detecting and quantifying harmful airborne substances.
