Gas leak detectors can help prevent dangerous situations caused by flammable or toxic gases. They can be used at home to detect sewer smell or gas leaks in pipes and appliances or by plumbers, landlords, construction workers, and others who use a combustible gas such as propane, methane or butane at work.

Choosing the right sensor is vital to your safety. You’ll want to know what kind of gas you’re dealing with, because a sensor designed for one type of gas cannot detect other gases. Also, location plays a big role in performance. For example, a sensor meant to detect gas heavier than air (such as Butane and Sulfur Di Oxide) must be placed lower down on the wall because these types of gases rise.
In addition to the sensor, a good gas detector will have an alarm that is clearly audible when activated. Typically, this alarm will sound in a high-pitched tone and may be accompanied by a flashing light or vibration. Some models will include a bed-shaker feature that is activated when the alarm goes off. This is a great option for those who wear hearing aids or are hard of hearing and will help wake them up.
Many models come with a battery, which is either disposable alkaline or rechargeable lithium-ion or nickel metal hydride (NiMH). Be sure to replace the battery when needed to ensure your device works correctly. You’ll also want to consider a model with an app-based alert system, which can send information to your smartphone via Wi-Fi or Bluetooth, for monitoring even when you’re not there.
