Inficon · Inficon-718-202-G1 Combustible Gas Detector
View on AmazonPrice and availability are shown on Amazon and can change at any time.
The Inficon-718-202-G1 is a combustible gas detector made in the United States by Inficon. The listing gives only package dimensions and country of manufacture, with no sensor type, detection range, alarm type, or power source published. That makes it hard to recommend over more fully specified alternatives like the Leakbee RV propane detector or the Aituzero refrigerant leak detector for most buyers. If you specifically need a US-made instrument and can obtain the missing specifications from the manufacturer, it may be worth considering, but the listing alone does not support a confident purchase.
What the Inficon Listing Actually Tells You
The Inficon-718-202-G1 is listed as a combustible gas detector under test instruments and gauges. The manufacturer is Inficon, and the country of manufacture is the United States. The package dimensions are 15 inches long, 3.9 inches wide, and 8.4 inches high. That is the entirety of the published data.
There is no sensor type, no detection range, no alarm threshold, no power source, no battery life, no operating temperature, no response time, and no calibration information. For a gas detector, those are the specifications that determine whether the instrument is suitable for a given job. Without them, you cannot know if it detects natural gas, propane, or refrigerant, whether it is a handheld sniffer or a fixed unit, or whether it alarms audibly or visually.
The package dimensions suggest a product that ships in a box roughly the size of a small briefcase. That tells you nothing about the instrument inside. It could be a handheld detector, a benchtop unit, or a kit with accessories. The listing does not say.
Where This Detector Sits Against the Other Picks
The site already covers three other gas detectors, each with a clearer purpose. The Leakbee RV Propane Gas Detector is a hardwired 12V DC unit with three mounting brackets, designed for RVs and similar spaces. The Aituzero Rechargeable Refrigerant Leak Detector is a handheld HVAC tool with a Japanese sensor and three sensitivity levels, aimed at refrigerant work. The HAOKESITE H2S Monitor Clip is a personal single-gas monitor for hydrogen sulfide, with a buzzer and clip.
Each of those listings publishes enough to match the tool to a task. The Inficon does not. If you need a detector for an RV, the Leakbee is the obvious choice because it is designed for that environment and powered from the vehicle. If you are servicing air conditioning or refrigeration systems, the Aituzero is the relevant tool. If you work in areas where hydrogen sulfide is a risk, the HAOKESITE is the specific safety device. The Inficon could be any of those things, or none of them, because the listing does not say what gas it targets or how it is used.
That is the central problem with this review: the product may be perfectly good, but the published information does not let a buyer make an informed decision. For a general introduction to the category, see what is a combustible gas detector.
The Specification Gap That Matters Most
For any combustible gas detector, the sensor type is the first thing to understand. Catalytic bead sensors, for example, respond to a wide range of combustible gases but can be poisoned by silicones and other compounds. Infrared sensors are more selective and longer-lived but cost more. The listing does not state which technology the Inficon uses, so you cannot judge its suitability for a given environment or its maintenance needs.
Equally important is the detection range and alarm threshold. A detector intended for leak pinpointing might respond to parts per million, while a safety alarm might trigger at a percentage of the lower explosive limit. Without a stated range, you cannot tell whether the instrument is a leak sniffer or a safety monitor. The listing is silent on both.
Power source and battery life are also absent. A handheld detector that runs on AA cells is used differently from a fixed unit that wires into a control panel. The package dimensions do not resolve this. The listing does not publish any of these details, and that is not a minor omission; it is the core of what a buyer needs.
How You Would Use It, and How You Would Not
Because the listing does not state the gas or gases detected, you cannot assume it will work for your specific application. A combustible gas detector is not a universal instrument. It may be calibrated for methane (natural gas), for propane, or for a broader range, but the listing does not say. If you need to detect natural gas, for example, you should confirm that the instrument is intended for that gas. The same applies to propane, butane, or refrigerant vapours.
Similarly, the listing does not state whether the detector is a safety device with an alarm, or a diagnostic tool that only displays a reading. A combustible gas sniffer is not a substitute for a carbon monoxide alarm, and a single-gas detector does not satisfy confined space entry requirements. Without a stated alarm type or certification, you cannot treat the Inficon as a life-safety device. It may be a fine leak detector, but the listing gives no basis for that assumption.

The Missing Maintenance and Calibration Information
Combustible gas detectors need regular calibration and bump testing to remain reliable. The listing does not mention calibration intervals, required gas mixtures, or whether the sensor is replaceable. That is a significant gap. If you buy a detector and cannot calibrate it, or cannot find out how, it may drift out of specification without warning. For a safety device, that is unacceptable. For a diagnostic tool, it is merely inconvenient.
The listing also does not state whether the instrument comes with a calibration certificate or any test documentation. The package dimensions suggest a boxed product, but the contents are not listed. You do not know if a carry case, batteries, or a calibration cap are included. That affects the total cost of ownership, even though the listing publishes no price.
If you are comparing detectors, look for ones that publish calibration requirements. The site has a guide to gas detector calibration kits that explains what is involved.
The Honest Verdict on the Inficon-718-202-G1
On the published information alone, the Inficon-718-202-G1 is not a detector you can confidently buy for a specific task. The listing gives the brand, the country of manufacture, and the package size, but omits every functional specification that matters. That is not to say the product is bad; it may be excellent. But a buyer cannot tell from this listing, and this review will not invent details to fill the gap.
If you have a specific need, the other detectors on this site are easier to match to a job. The Leakbee is a clear choice for RV propane detection. The Aituzero is aimed at refrigerant work. The HAOKESITE is a personal hydrogen sulfide monitor. Each publishes enough to make a decision. The Inficon does not.
If you are determined to consider the Inficon, contact the manufacturer or a dealer and ask for the full specification sheet, including sensor type, detection range, alarm type, power source, and calibration requirements. Without those, you are buying blind. For a broader view of the category, see best combustible gas detectors.
Should You Buy the Inficon-718-202-G1?
Only if you can obtain the missing specifications from another source and they match your needs. The listing alone does not provide enough information to recommend this detector over the better-documented alternatives on this site.

Frequently Asked Questions
What gas does the Inficon-718-202-G1 detect?
The listing does not state which combustible gas or gases the detector is calibrated for. It is described only as a combustible gas detector. You would need to confirm with the manufacturer whether it targets natural gas, propane, or a broader range.
Does it have an alarm?
The listing does not state whether the device includes an audible or visual alarm. It may be a leak detector that only provides a reading, or a safety device with an alarm. Without that information, you cannot rely on it as a life-safety alarm.
Is it suitable for RV use like the Leakbee?
The listing does not state the power source or mounting options, so it is not possible to say whether it is suitable for RV use. The Leakbee is specifically designed for 12V DC RV installation and publishes that information.
How is it powered?
The listing does not publish the power source. It could be battery-powered, mains-powered, or hardwired. This is a critical omission for anyone planning installation.
Does it come with a calibration certificate?
The listing does not state what is included in the package beyond the dimensions. It does not mention a calibration certificate, test gas, or any accessories.
Where is it made?
The listing states the country of manufacture is the United States, and the manufacturer is Inficon.
