10 Best Gas Leak Detectors Reviewed & Rated

The U.S.A consumes a mindboggling 27 quadrillion cubic feet of gas annually, and though it seems like an immense value at first, it makes sense considering all we do with gas. We use natural gas to produce power, heat our home and heat water seeing as natural gas water heaters are some of the best in the market. However, though the benefits are abundant natural gas is also dangerous.

Between 2007 and 2011, the U.S fire departments responded to about 51,600 fires annually caused by flammable gas. These fires resulted in 168 civilian deaths and property losses to the tune of $644 million. Most of these fires could have been prevented were it not for the misconception that you can smell the gas leaks. Natural gas is odorless, and the distinct smell is a chemical that vendors add. However, with a gas leak detector, you can identify gas leaks and mend your pipes in time.

A gas leak detector is useful for both industrial uses and homes. Industrial gas detectors pick minute gas leaks or any fluctuations in pressure levels while they check the presence of one or two gases at home. Gas leak detectors are typically complex tools and use semi-conductor sensors that help identify a gas and the exact area. They are visual units but include an auditory system that buzzes when there is a leak.

Gas detectors are also used to identify a leak, and to ensure there are no leaks. Ensure you expose the sensor to a previously known gas concentration to tell whether the device is working. A challenge test is also recommended as only then can you know if it is of use. However, with the many units in the market, picking a quality gadget could be a challenge. However, below is a buying guide and our recommendations.

Gas Detectors Selection Criteria

  • Gas type – Though LPG, propane, and natural gas are the most common petroleum products in most households; there are instances where you find methane, CH4, coal gas, and butane. Also, there is rarely a one size fits all gas detector and you need a unit that is compatible with the petroleum product in your house or industry.
  • Power indicator – Most gas leak devices are battery powered. This is advantageous in that you do not run the risk of it dying on you, and they are cheap to run. However, ensure that the battery-power indicator works alerting you when batteries are almost depleted.
  • Display – Invest in an appliance with a bright screen, so tweaking of the settings is easy. Moreover, ensure it has a back.
  • Alarms – Most gas monitors use flashing lights or audible alerts; whichever you prefer, ensure it is loud or bright enough to be heard from different parts of the house. We recommend you get a gas detector with flashing lights if one of the residents has a hearing impairment. However, an audible alarm is best for visually impaired persons. Moreover, your preferred pick should include a headphone jack when working in areas where silence is paramount, say schools, and they should be mutable.
  • Durability – If you intend to keep your unit running, say in a restaurant, ensure it is durable. Also, it is best you get a monitor that uses electricity but with a battery backup to avoid risk should batteries run out.
  • Sensitivity – The sensitivity of your detector will depend on the sensor used on the tip of your wand. Industrial units will need a gadget with a higher sensitivity to detect minute leaks. Sensitivity is measured in parts per million and ensure you purchase a device with the necessary.
  • Warranty – Always check with the company and ensure they have a comprehensive warranty. Unless you are satisfied with the warranty, refrain from purchasing the device.
  • Extra features – These are good to have but not necessary. You can invest in an appliance with auto-power off as it helps conserve the battery. Moreover, get a tool with automatic calibration so it ready to go straight out of the box. Finally, consider the probe length, though they are relatively the same.

FAQS

Why are there more seepages during winter than summer?

Though gas leaks can pop up at any time, they are more popular I winter than in summer owing to the thawing and freezing of the ground that causes it to shift. If not repaired, they might seep into your house leading to an explosion. Nonetheless, you should always be on the lookout for gas leaks but be more vigilant during winter.

What should I do when I smell a gas leak?

First, get out of the house and go to a safe area. Don’t turn appliances on or off including flashlights as they can produce a spark causing an explosion. Also, don’t start your car, and do not smoke. When you reach a safe area, call 911 and your utility company to contain the situation.

What are some sources of hazardous petroleum gases at home?

The US economy is built on petroleum, and thus there are various sources of petroleum gases around us. Some common sources include CFCs from fridges, septic tank gases, cleaning agents and disinfectants, chlorine, ammonia, and tear petroleum products.

How can I know if I have a gas leak?

The best way to tell if there is a leak in your home is to use a gas leak detector. However, you can be on the lookout for the following conditions. First, check if flames are a lazy yellow and not the standard blue. Moreover, check for excessive condensation on appliances, and black stains in your domestic devices. Also, you can have an expert visit your property semi-annually to assess the condition, and don’t use appliances beyond what they are made for.

What happens in the event there is a seepage?

Seepages are dangerous, and any of the following can happen. First, there can be an explosion especially if it is in a small room that lacks ventilation. Moreover, it can cause a fire seeing as petroleum products are highly flammable, and finally, it might result in weak plants. The latter should be one of the first signs that you leak.

Why do gas leaks happen?

Well, there are some reasons, given the conditions. Outside leaks are a result of pipe corrosions due to exposure from the elements and cracks from shifting of the ground. Pipes can also be damaged during excavations or floods. Always ensure you contact your utility company before you begin excavation or construction. As for indoor leakages, often they are a result of loose fittings and cracked pipes. Indoor leaks can also be caused by faulty gadgets.

What are the signs of Co poisoning?

Carbon monoxide is odorless and thus is difficult to detect. Having a gas detector is handy but be on the lookout for the following: headaches especially when standing up, fuzzy vision, tired of sitting upright, a sick stomach, and finally, the symptoms disappear when you leave the house.

Conclusion

Wrapping up, we think the UEI CDA1000A is our best pick, and for home use and light work, but the MSA is the best for industrial use. However, ensure you stick within your budget but still, get the most value. Finally, be sure to leave your thoughts in the comments below.
