Which tool is used to detect gas leaks?

The gas leak detector is specifically designed to identify the presence of gas leaks in various settings. These tools use sensors that can detect different types of gases, often including natural gas and propane, by measuring the concentration of gas in the air. When used, they can often provide real-time feedback, allowing for immediate action to prevent potential hazards such as explosions or poisoning.

In contrast, the other tools mentioned do not serve this specific purpose. For instance, a moisture meter is utilized to measure moisture levels in materials, which has no relevance to gas detection. A thermometer is designed to measure temperature, providing no information about gas leaks. Lastly, a pressure gauge measures the pressure of gas or liquids within a system, but it does not diagnose or detect leaks themselves. Therefore, the gas leak detector stands out as the essential tool for ensuring safety and compliance in environments where flammable or hazardous gases may be present.
