The Forensics Gas Leak Detector is a handheld combustible sniffer with a catalytic sensor and flexible probe that detects an unusually broad range of combustibles - natural gas (methane), propane, butane, gasoline and alcohols - and passes a 10-foot drop test — it traces a leak to its source; it does not measure whether the air is safe.

Why the Forensics Gas Leak Detector covers a broad range of fuels
Most combustible sniffers are tuned for natural gas and propane — but a crew that also works around gasoline, solvents and alcohols wants one tool that sees them all. The Forensics Gas Leak Detector does that: a handheld with a catalytic sensor and flexible probe that sniffs an unusually broad range of combustibles (natural gas/methane, propane, butane, gasoline and alcohols), in a body rugged enough to pass a 10-foot drop test. As gas leak detectors go, this is the broad-range rugged pick, and the best gas leak detector guide and the gas detection guide explain where it fits. It traces many kinds of fuel leak with one tool.
Safety first: a leak detector pinpoints a leak; it does not continuously guard an occupied space — pair it with an area or personal monitor for that. And a gas detector alarms, it does not protect: in an IDLH or oxygen-deficient atmosphere you must evacuate and use supplied-air or an SCBA, because a monitor is not a substitute for respiratory protection. A combustible leak is also a fire and explosion risk; eliminate ignition sources and confirm the detectable gases on the listing.
What the Forensics Gas Leak Detector listing documents
From the published specs: a handheld combustible sniffer with a catalytic sensor; a flexible probe; coverage of a broad range of combustibles (natural gas, methane, propane, butane, gasoline, alcohols); and 10-foot drop-test durability. These are true combustible gas leak detector and catalytic leak sniffer credentials in a broad-range gas detector. Confirm the detectable gases on the listing.
How the Forensics Gas Leak Detector compares to other gas detectors
For a color-display combustible sniffer, the TopTes PT-830S; for a value gooseneck sniffer, the TopTes PT520A; for a pocket %LEL sniffer, the TopTes PT210S; for a refrigerant sniffer, the TopTes RT-389; and for a fixed combustible-area monitor, the Forensics EX LEL Wall-Mount. The best gas leak detector guide and the combustible detector vs leak detector guide help you choose.
Choosing the right detector

Browse the gas detectors, gas leak detectors, and combustible gas detectors collections; for area and personal safety monitoring, the area gas monitors and personal gas detectors collections; and for the leak-versus-monitor decision, the 4-gas vs single-gas guide and the calibration accessories collection.
Where it fits by job and crew orders
The Forensics Gas Leak Detector suits fuel-system, gas-line, and solvent-handling crews who need one rugged sniffer that covers many combustibles — see the gas detection guide and the portable gas detectors collection for the safety monitors a crew also carries. Its broad catalytic sensor and drop-test build suit crews that see a mix of fuels and rough handling. Confirm the detectable gases on the listing, keep the probe tip clean, and replace the sensor at its service interval.

Frequently asked questions
What is the Forensics Gas Leak Detector?
A handheld combustible sniffer with a catalytic sensor and flexible probe that detects an unusually broad range of combustibles - natural gas (methane), propane, butane, gasoline and alcohols - and passes a 10-foot drop test.
What gases does it detect?
A broad range of combustibles - natural gas (methane), propane, butane, gasoline and alcohols, and more. Confirm the full list of detectable gases on the listing for your application.
What is a catalytic sensor?
A catalytic (pellistor) sensor responds to a wide range of combustible gases and vapors, which is why this detector covers more fuels than a narrow sensor. Confirm the sensor and coverage on the listing.
Is a leak detector the same as a gas monitor?
No - a leak detector pinpoints a leak; it does not tell you whether the air in a space is safe to breathe. For that you need an area or personal gas monitor. Confirm your program's requirements.
Is it a substitute for respiratory protection?
No - a leak detector is a tool for finding a leak, not respiratory protection. In a hazardous atmosphere you must use the correct respiratory protection. Confirm your program's requirements.
How durable is it?
The listing states it passes a 10-foot drop test for real jobsite use, so it survives being dropped on a hard floor. Confirm the durability rating on the listing.
What does the flexible probe do?
The flexible probe reaches behind and under appliances, tanks and fittings to trace a leak into tight or awkward spaces. Confirm the probe length on the listing.
How is it powered?
Confirm the power source and run time on the listing; a catalytic sensor draws more power than some sensor types, so plan for your checking volume.
Who is it for?
Crews that check for a wide mix of fuel leaks - gas lines, fuel systems, solvent stores - and want one sniffer that covers many combustibles.
How do I use it to find a leak?
Move the probe slowly along suspected joints, tanks and connections; when the alarm climbs, narrow your search to pinpoint the source. Confirm the procedure on the listing.
How do I care for it?
Keep the probe tip clean, charge or replace the power source as needed, store it per the manual, and replace the sensor at its service interval to keep it responsive.
How do I order for a crew?

Works great, sensitive, descrete readings, easy to use
This little meter works great. Used it to pinpoint a tiny natural gas leak at the back of a range, probably since it was installed two years ago. Well worth it. Appears sensitive (picked up natural gas at a level below what my wife and I could smell), has a nice digital readout, simple to operate.My wife and I would very occasionally smell a trace of gas near the range, but could not pinpoint it. The majority of the time we could smell nothing no matter how hard we tried, and assumed it was associated with the small amount of gas that would escape before the burners lit. I grew suspicious, and bought this meter. Immediately it detected the hotspot was where the range met the wall at the back. I pulled out the range, and the hose and valved looked new and in good shape. Further detective work with the meter narrowed it down to the connection at the valve. I unscrewed the hose and found that the installers didn't use tape or pipe thread compound! Added gas pipe tape, screwed everything back together, and all is good as confirmed by the meter. Nice product!

Easy to use and detect gas leaks
It was able to confirm the leak I thought I was smelling, however it was quite slow in response and hard to pinpoint the exact source. The display is nice and easy to read, and the instructions are pretty straight forward.

Worked Perfectly to detect a gas leak
I had a slight gas leak from an oven which I was trying to locate. There was sometimes a faint smell of gas in the house. I could smell it from the back of the oven but I couldn't determine, using my nose, if it was a lose connection or a sticking valve.Originally I bought a cheap gas detector from the PANGAEA brand for $25. This had a range of 0 - 10,000 ppm but it's sensitivity was terrible. I zeroed it outside the house but the only gas it would detect was if I switched a burner on.This Forensics detector is amazing. I zeroed it outside the house again. As soon as I bought it inside the house it registered 70 ppm. It was sensitive enough that I could hold the sensor over the various connections and pin down the leak to the valve going to the oven and not the broiler.It's 4x the price but it works. The ability to zero the readings, switch the sensitivity between high and low and to switch the buzzer off are useful. It's small and feels good in the hands with the rubber finish.I wish the display was a bit brighter and I don't like that the battery compartment is held in place by a screw. This isn't going to be used very much so I don't want to leave the batteries in it all the time. Having to find a screwdriver to open the compartment is an inconvenience.

Extremely useful, detected a leak that PSE&G did not detect in 2 attempts! (Tips at end)
(see Tips at end)I purchased this because we smelled gas in the basement, but PSE&G could not detect it with their meter. I calibrated it and it was detecting gas *everywhere* inside. That made me skeptical, so I put it to the stove burner (running but not lit) and it pegged high. I put it outside and it went back to zero. So I felt like it was working.After checking the whole house, I isolated the highest readings to the gas water heater. I did not see the pilot tube corrosion because it was under the tube not on top. I called PSEG again, another guy shows up and commented the Forensics meter is "too sensitive to be useful".Well again, his meter didn't pick up anything in the house. I bring him to the water heater and his meter is STILL not getting anything (!). I showed him 2 places I was getting very high readings, the thermostat and the exhaust up top. After like 10 minutes, he visually locates the corroded pilot tube . Long story short it got fixed and now my Forensics meter reads ZERO all around the house including the water heater. Despite my concern it was accurate the whole time.I have decades of experience with high-end electronic test equipment. My expectations were low for this being only $100. But this meter proved itself against the big boys, it may not read the exact PPM, but it's a useful relative indicator and you can trace a leak with it. I'm sure this will come in handy again.TIP 1- based on the reviews of people breaking it, I am VERY careful with it. It's weighted kind of awkward due to the top heavy sensor so just treat it like it's a Champaign glass. I carry it from the tube so it's balanced.TIP 2- make sure you calibrate it outside where there's zero gasTIP 3- natural gas rises and it's shocking how much that tiny leak filled the house with detectable gas! Do not be surprised if you get readings far away from the source of the leak!

got to use it once.
I spent a little extra to have this device in my inspection belt and the quality seemed worth it until the second time I went to pull it out when I realized that the metal tip had unscrewed itself and the sensor had fallen out. Pretty bummed to have wasted nearly $100 for something that is now useless. So much for spending a little extra to have a reliable tool...

A worthwhile addition to my toolbox
This product is great for checking my kegerator for R290 leaks and made the job easy and safe. I used it to repair my commercial kegerator which needed a re-charge of R290 refrigerant. R290 is purified and dried Propane gas and it is important to do a leak test with the detector before, during and after recharging.This was a quick repair/recharging and I saved a lot by buying this rather than calling out a repair person. It was the most expensive part of the kegerator repair, but the detector is well made and I am sure will give many years of service. It's Amazing how sensitive it is to very small amounts of explosive gas. I tested it on the BBQ and even a quick 1/2 second twist of the control to release gas was detected by this unit. Thanks!

The tester worked immediately!
My Wife and I have a natural gas fireplace in our basement. Every once in a while, we can smell natural gas coming from the area of the fireplace. ( fireplace is shut off for the Summer months). We could never detect where the gas leak was at. Until now! The Forensics Gas Leak Detector has great accuracy! The Gas Leak Detector is very easy to use. I took the unit outside and installed the 3 supplied batteries. I then turned the tester on, and let it calibrate itself. Turned the tester off. Now back inside our basement, I turned the tester back on. I put the sniffer at the base of the fireplace. Within a few seconds, the tester’s alarm went off! The natural gas was leaking at the gas shutoff valve going into the fireplace. Will need to install a new natural gas fireplace safety valve. Great value for the money. I should be able to do the repair myself. Edward M
