Here we review the best gas detectors to buy in 2014.

Gas detectors are safety instruments which are used to detect and monitor levels of gas in the atmosphere. Various different gases can be checked, typically they are either toxic, combustible, or flammable and present a threat to human safety or life. Detectors can be portable or fixed in one position (stationary). A portable gas detector is for protection of personnel and monitors the air in the surrounding atmosphere, a stationary detector is normally fixed to a wall or in a panel and is electrically powered. Applications include construction, fire and rescue, petroleum refineries, sewage treatment, mining, paper mills and tanneries.

The following are the top 5 gas detectors currently available on

Starting with #5…

#5 = BW Technologies GAXT-X-DL-2 GasAlert Extreme Oxygen (O2) Single Gas Detector

BW GAXT-X-DL-2 Gas Alert Extreme Oxygen

First up we recommend the GasAlert Extreme oxygen detector, a single gas detector for measuring oxygen levels. There’s a low level alarm set at 19.5% by volume of oxygen and high level at 22.5% but these levels can be adjusted. BW Technologies are renowned for some of the best safety instruments on the market – high in durability, reliability and accuracy. Perfect for use in the mining and construction industries as well as for the emergency services and other potentially dangerous settings such as confined spaces. The strong and robust casing is water resistant and will stand up to the most taxing of circumstances. The meter’s reliabilty is maintained by regular self-testing and it is designed to give effective and reliable performance even in extremely harsh environments. Data logging and management facilities are available – as well as a loud 95 decibel alarm, visual and vibration alerts – the meter records alarm events and can transmit them via a USB datalink.


#4 – V!sa 4 Gas Monitor

V!sa 4 GasMonitor

Nobody can put a price on safety so if that is your priority then you should consider the V!SA Portable Multi-Gas Analyzer. This detector is a bit more expensive but if you are looking for a high-end meter at a reasonable cost this is the one for you. The V!SA can display the readings for up to five different gases using “plug and play” sensor technology, selectable from a wide range of available sensors including Carbon Dioxide (CO2), Flammable gas (LEL), Carbon Monoxide (CO) Sulphur Dioxide (SO2) and Hydrogen Sulphide (H2S). The detector is certified for use in hazardous areas and has ATEX II 2 G EEx (iad) IIC T3/T4 certification so it can be used in the harshest of environments and is suitable for many industries such as petrochemical, marine, nuclear pulp and paper, refining, steel, chemical, construction, defence, electricity, brewing and food. This high quality instrument has 95 dB audible and 360-degree visual alarms, data logging capability, program menus and can be password-protected for multiple users. It comes complete with a charger.


#3 – Fixed Gas Detector, C3H8, CH4
Safe T Alert Fixed Gas DetectorNext we have selected the Safe T Alert fixed propane gas and natural gas detector, a must-have appliance if you cook or heat your home using propane gas or natural gas. Both Propane gas and natural gas can result in fires or explosions if they leak and are exposed to a source of ignition. The 40-411-P can be mounted in most locations and is fixed near the floor – where heavier propane gas will gather in the event of a leak – using either screws or velcro. An alarm should be fitted near to every appliance that uses gas, also consideration should be given if you live near a waste disposal area or pit as these produce natural gas which can find their way into your house. The unit comes with a decent length of electrical cord and plugs right into a 120V AC mains supply outlet.


#2 – Bacharach Leakator Jr 0019-7075 ABS Plastic Combustible Gas Leak Detector

Bacharach Leakator Jr 0019-7075 ABS Plastic Combustible Gas Leak Detector

Runner-up in this section is the Bacharach Leakator Jr, a combustible gas leak detector. This tool is brilliant if you are working in the plumbing industry or other related jobs like HVAC installation or maintenance but is also perfect for the gas industry – inspecting valves, meters and regulators and surveying pipelines, as well as the general building trade and construction industries. The detector easily pinpoints even small gas leaks without any calibration being required so it is very low maintenance. The unit itself is only 6 inches long and has a flexible probe which extends a further 12 inches. It has a loud warning sound on gas detection and two levels of sensitivity, for finding the approximate area then spotting the exact location of the leak. Not only can this product protect you from a costly insurance claim, it can save the lives of you and your customers.


#1 – BW Technologies GA24XT-H GasAlertClip Extreme 2-Year Detector

BW Technologies Single Gas Detector Hydrogen Sulfide  Part Number GA24XTH

The best gas detector we found for all round performance and value was the BW Technologies GA24XT-H. It is a handheld detector used to monitor levels of hydrogen sulfide (H2S) in the atmosphere and can operate continuously without recharging, battery replacement or recalibration for up to two years. There is a triple layer of warning alert with audio, visual and vibration alarms all operating on high (or low) gas level. The user-adjustable LCD screen clearly shows all the information you need; alarm set-points, alarm level, detector life remaining and maximum exposure among others. This meter is an essential piece of safety kit in a wide range of applications – petroleum refineries, sewage treatment plants, paper mills and tanneries to name a few. The detector can output its results to a printer or computer and has a belt clip on the back for hands-free operation.
