Which device is commonly used to detect leaks in gas piping before activation?

Explanation:
Detecting leaks in gas piping before activation is done with a leak detector. This device senses the presence of combustible gas in the air around joints and fittings and alerts you with an alarm or indicator, so you can fix any leaks before turning the gas on. It provides immediate, ongoing detection and is designed specifically for locating leaks quickly and safely. While soap solution can reveal leaks by forming bubbles at a leak, it is a manual method rather than a dedicated device. A gas meter measures usage, not leaks, and a thermometer measures temperature, which doesn’t indicate gas leaks.
