Natural gas leak detectors  may not be as common on the list of must-have items for the home as smoke detectors and fire extinguishers, but they are an important and affordable addition to your safety arsenal. Leaking combustible gasses like natural, propane and butane can create a number of dangerous situations from explosions to asphyxiation, and they can be difficult to spot because they are colorless, odorless, and flammable. Having a quality device that detects leaking combustible gasses like natural and propane is the best way to keep your family safe.

Generally, these devices use a sensor to monitor the concentration (PPM) of a certain gas and then alert you when the level becomes too high. Many of these detectors can also detect carbon monoxide, which can be deadly even at low levels. With advanced sensitivity, these detectors can often warn you before you might be able to smell the escaping gas, giving you ample time to act.

Natural Gas Leak Detectors: Safeguarding Your Home from Potential Disasters

These devices are a great option for homeowners and professional contractors alike. Some are battery-powered while others plug directly into the wall. They are easy to use and offer indicator lights that indicate if the detector is sensing a combustible gas. They can also have a siren, light or voice alarm that goes off if the concentration of combustible gas reaches a preset level.

Some models are designed to help you pinpoint the source of the gas leak, but this can only be done by spraying a detection solvent on the area and watching for bubbles. The UEi Test Instruments combustible gas tester is one model that gets high marks from Amazon reviewers for being easy to use and with an extra-long 18-inch probe head for reaching hard to reach spots. It also comes with a oxygen-O2 sensor for precise leak pinpointing.
