Hazardous gases can be a real danger in the home and workplace but there are various different gas detectors covering all the dangerous gases you may find. As well as gases that can cause explosions or fires, there are other deadly dangers from poisonous gases in the home. Carbon monoxide and radon are both referred to as “silent killers” as they are impossible to detect without a gas sensor, below are some great recommendations as to gas detection kit that you can buy today to keep your home, office or school safe from these killers.

The hazardous gas detectors shown below are calibrated under laboratory conditions to ensure that they are accurate and reliable.

#5 Kidde KN-COPP-3 Carbon Monoxide Alarm


Carbon monoxide poisoning is one of the main causes of domestic accidental death by poisoning in America but it can easily be prevented in your home by installing this Kidde KN-COPP-3 Carbon Monoxide Detector. CO gas levels can reach deadly levels without you realising it as it is an odorless, colorless gas which can be released by domestic appliances and office equipment. CO poisoning symptoms are difficult to spot and can often go undetected, being similar in nature to common illnesses like the flu. It is therefore essential to have at least one CO monitor/alarm system in place in your home – and indeed it is now compulsory in some areas. This unit plugs directly into your AC power outlet and has a battery back up which takes over automatically in the event of a power failure. Carbon monoxide levels are monitored continuously and you can see in an instant what they are on the digital display, a loud beeping alarm will sound if a dangerous level of gas is reached.


#4 UEi Test Instruments CD100A Combustible Gas Leak Detector


The UEi Test Instruments CD100A Combustible Gas Leak Detector is a professional standard instrument designed for service engineers to enable them to detect combustible gas leaks in the home and commercial premises. But at an average cost of $100 to call out a plumber or furnace repair man, the unit pays for itself in one use. This gas detecting device will pinpoint even the smallest leak, right down to which side of a joint the leak is on – even when the use of more traditional methods prove ineffective. If you use any of acetone, benzene, butane, propane, toluene, methane, ethylene, gasoline, halon, hydrogen sulfide, solvents, thinners, or refrigerants remember that there are no safety circuit breakers to trip like you would get in an electrical system. The detector is simplicity itself to use, there’s nothing complicated to try and work out, just switch it on and listen for an increase in tick rate.


#3 TIF Instruments TIFXL-1A Refrigerant Leak Detector



Refrigerant Leakage is a very serious hazard in commercial and industrial premises where refrigerators are used and to a lesser extent in the home. Indeed because of the dangers of refrigerant gases getting into the atmosphere, all refrigeration equipment needs to be properly disposed of. The TIF Instruments TIFXL-1A refrigerant leak detector can detect all halogenated refrigerants, including fluorine and is part of the new range of gas leakage equipment with the brand “Generation X”. The company says that they have completely redesigned the instrument both aesthetically on the outside and internally with a new microprocessor based operating system. The redesigned sensor tip gives increased sensitivity and reliability and sends 2000 signals per second back to the internal computer. This machine has had some very positive reports from customers and is our top rated refrigerant detector.


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

Our runner-up selection in the gas monitoring section is the Bacharach Leakator Jr. Combustible gases such as butane, methane, acetylene and those given off by gasoline, paint thinners, solvents etc are any gas that can cause fire or explosion and can obviously be deadly in the home or workplace. This is a very compact and portable combustible gas meter at only 6 inches long, but coming complete with a 12″ extension hose for extended reach to check for small pockets of gas in awkward, hard to reach spots. Featuring dual sensitivity for detecting gas in the wider area then pinpointing a leak in a pipe for example. A fully portable unit, the Leakator gas indicator is simplicity itself to use and can pinpoint large or small leaks whilst needing no calibration whatsoever.


#1 Corentium Home Radon Detector by Airthings 223Corentium Home Radon Detector by Airthings 223 


Radon gas is known as the silent killer and the Corentium Radon Gas Detector will help to protect you, your family and your workplace from its dangers. Radon is a radioactive gas that is given off naturally from rock and gets into houses at the lowest points – for example foundations, water pipes, cracks in walls at low level and cavity wall insulation. One of the problems of modern very highly energy-efficient houses is the lack of ventilation, this can lead to a build-up of radon as the gas lies at low level and once it is in the house does not have a means of escape. Good radon gas testing kit is essential to detect dangerous levels of the gas and allow you to keep your family safe. This instrument is the most advanced electronic radon gas detector available as a handheld unit at an affordable price. Don’t take a chance with potentially dangerously high levels of radon in your home, in your school or in your workplace when the Corentium lets you monitor average radon levels over 1 day, 7 days and a year – all at the same time. This is a very accurate machine with only a 5% error band and is extremely energy efficient – it will run for up to 3 years on one set of batteries. Recalibration isn’t a problem either as it is not required for the whole lifetime of the meter. Another big plus point is the simplicity of use, you literally don’t need to do anything other than insert the batteries and press the reset button for the monitor to display all the information you need. Other radon testing equipment is single use but with this kit you can reset it and reuse, saving a lot of money against the cost of expensive professional radon testing services.
