Things to consider when buying a gas leak detectors

Gas leaks are detrimental and as much as using a gas sniffer can help you detect any leakages, a poor quality device can cause massive destruction of property. To ensure you get the right tool for the job, we have written a detailed shopping guide on what you should be on the lookout when shopping for you gas sniffer.

Type of gas the sniffer can detect

The reasons why most people complain about gas sniffers not detecting gas leakages is because they invested in the wrong tool. All gas sniffers are not the same and are dedicated to sensing specific gases. Most manufacturers list the type of gases the detector can sense.

So before even spending on a gas detector, ask yourself the type of gas you would like the device to sniff.

Application area

Different gas leak detectors are designed to be used on different applications. For commercial application, you should consider choosing a tool which can run for longer. If you need one to use for outdoor applications, you should go for a device which can withstand harsh conditions without compromising on accuracy.

Temperature range

Each gas sniffing tool is designed to work under specified temperature limits. If you stay in extremely cold or hot areas, you should take a look at the tools specified temperature limits to minimize any frustrations.

Temperature range does not only apply during operation but also for storage. Storing your tool under wrong temperature range will damage it or interfere with its performance. Always be cautious and ensure all the conditions have been met.

Accuracy

Accuracy is critical. An inaccurate gas sniffer will always give you wrong results. Though it may be hard to determine the accuracy of your device by just looking at it, taking advantage of the pre-calibrated gas sniffers or reading reviews from customers who tried the product can helps have an idea of the device accuracy levels.

Features

Modern gas sniffing tools are constructed using the latest technology. However, do not assume. Different devices have varied features and your choice should be fueled by the features you are looking for.

Ease of use

Choosing a gas sniffer that is hard to use will make your life more miserable. Worse still, you find that you cannot operate it or use it because you do not have any idea how to how navigate through. A good gas detector should be user-friendly with easy to reach menus.

Power consumption

Most people pay attention much to getting a quality gas sniffer that they forget power consumption levels. This is a very critical aspect that should not be overlooked. If your device is battery operated, get to know the number of batteries needed for it to operate and how long it will take before the cells call for a replacement.

For industrial application, rechargeable or longer battery life helps run the tool without any challenges. For electric gas sniffers, get to know the wattage. If you may be looking forward to reducing your power bills, you should take advantage of energy efficient sniffers.

Final Verdict

No one can predict when their gas will leak and it is not good to take chances. Do not wait until you suffer losses for you to think about buying a gas sniffer. These devices are affordable, reliable and convenient. While there are varied brands to choose from, always ensure that the device you choose is of good quality. All the best gas leak detectors we have reviewed are an excellent choice if used for the recommended applications.
