Best Gas Leaks Detectors Buying Guide

From the price comparison, little is deduced of the functionality of a gas detector. Especially for appliances intended for domestic use, these are low-cost items. The models that you find in the ranking stand out on the excellent performance confirmed by users who have tested them daily, but also for the often meagre cost.

The Gases Detected

What you need to pay attention to is the type of gas that the appliance can detect. The technical functioning at the base of the detector, a physical process often much more complex to explain than not to be used, can identify only specific types of gas and not all “dangerous” ones.

Specific detectors exist to identify an alarming concentration of carbon monoxide. This gas is released during combustion: for example, when using wood or embers to heat an environment without providing the correct exchange of air, the combustion that releases CO ends up replacing oxygen and becoming deadly.

There are several devices capable of detecting gas leaks from the pipes. In these cases, the sensor can recognize the type of concentration of rarefied or liquefied gases such as methane, propane or butane.

They are the ones most frequently used in the home to power the water heating system or for cooking. An escape of these substances must be detected before it becomes dangerous, and the devices are often able to signal also in what concentration they recognize the danger.

Operation Reporting System

The review of the models highlights a fundamental aspect, i.e. the ability of the device to also report its operating status. It is essential to be able to count on a device that is always operational and capable of warning even of a sudden shutdown.

As a rule, different coloured LED lights are responsible for reporting various information, including the correct functioning of the device or the exhaustion of the battery, in the case of models not powered directly by the power supply.

Correct Installation

The best brand of gas leak detectors provides precise indications on how to install the appliances. For each safety device, the correct positioning constitutes the difference between a reliable detection or not.

The liquefied gas is heavier than air and therefore will tend to settle towards the ground, the right position for this type of detection is between 50 and 20 cm above the floor. Gases such as methane are lighter than air and therefore tend to rise upwards, in that case, 20/50 cm from the ceiling.

Who installs the device knows what type of leak to monitor and then invests the detector in the right place. The distance from air vents or ventilation points is also essential because it will not be in these areas of the house that the highest concentration of any dispersion will occur.

Reliable

The first thing the user looks for in an appliance like that to detect the presence of gas and other toxic substances is reliability.

Well, those who bought Beghelli’s Senti Gad Duo have received confirmation that it works really and quickly. Don’t worry, it’s not that everyone suddenly had a gas leak; much more simply they performed a simple test suggested by the manufacturer.

The test as mentioned above, consists in placing a lighter near the detector and letting out a little gas. Even if the amount of gas is minimal, it is sufficient to trigger the alarm. This simple test immediately convinced users of the goodness of the tool.

In addition to LPG gas, the detector recognizes methane and carbon monoxide. The latter is a ruthless killer who kills in his sleep without the poor victim realizing what is happening.

Easy to Install

Another undeniable strength in addition to its effectiveness in detecting threats of gas and monoxide is the ease with which the detector is mounted. It is not necessary to resort to a specialized technician: fix it to a wall respecting the minimum measures that you find explained on the instructions and insert the plug into the socket.

Once this is done there is only the lighter test we mentioned in the previous paragraph to test that everything works correctly.

In the event of a threat, there is a clearly audible acoustic signal. If that is not enough, there is also a visual indicator: if the LEDs are green, everything is normal. The red colour, on the other hand, indicates the presence of gas in the air while in the event of a malfunction of the detector, a yellow light turns on.

A Little Dated

Although still on the market we have to say that this detector is a bit dated, let’s say it dates back to the early 2000s. Hence, it is not really the latest technological innovation in the sector. Still, as mentioned, it works very well.

That this is not a very recent production device is also evident from the dimensions which, according to some, are too generous.

In short, it is cumbersome. Another small complaint to be made concerns the instructions which are rather synthetic. However, we must still say that the use of the detector is straightforward.

We are satisfied with the build quality. You can immediately see that the detector is reliable and made with suitable materials, worthy of the Beghelli tradition.
