Freon Leak Detectors, Refrigerant Leak Detectors & AC Leak Detectors
Forensics Detectors offers sensitive Freon Gas Leak Detectors for inspectors, homeowners, landlords, engineers, and technicians for refrigeration leaks, AC leaks, industry, and property protection.
Freon Leak Detector
Maximum Sensitivity
The Forensics Detectors Freon Leak Detector delivers uncompromising refrigerant leak detection for HVAC professionals, mechanics, technicians of home and vehicle owners. Powered by a Japanese heated diode semiconductor sensor with industry-leading 0.1oz/yr sensitivity, this detector identifies leaks across all refrigerant types including CFCs, HFCs, HCFCs, HFOs and combustible gases like methane and propane.
Refrigerant Gas Detection
HFC: R134a, R410A, R407C, R417A, etc. HCFC: R22, R123, R141b, R402a, etc. CFC: R11, R12, R13, R502, R503, etc. PFC: PFC-14, PFC-116, PFC-218 etc. HFO: R-1234YF, Others: R717 & halogen mixed refrigerants
Are Freon Gases Dangerous?
Freon gases can be dangerous in several ways. They can displace oxygen in confined spaces causing asphyxiation, cause frostbite upon contact with skin in liquid form, and produce toxic byproducts when exposed to high heat. Some Freons damage the ozone layer and contribute to global warming when released into the atmosphere.

Just did a couple of diy mini split installs. I have plans to install lots more in properties i'm renovating. I'm using cheap units, expensive units require a certified hvac tech to install to validate the warranty. For the price of that i can buy cheap units all day long and often. However if i had a leak or no cold air after a short while even if under warranty for the diy cheap units i'd probably just send an email (not expecting much traction) but plan on tossing it. How else could I prove a leak was in my line set flaring and connections or the head unit, condenser, etc without lots of other diagnostics tools to isolate that. I figure at least this lets me smell around a fresh install to confirm my bubble test at line sets and at least check other areas around the inside unit as well around the condenser. It at least gives some evidence that the fault is not mine but their unit.To test it i tried cracking open a self sealed can of r134a and detection was positive. Also on my next mini split install i just cracked the high pressure line set, and the release refrigerant valve slightly for a short bit. It didn't take much to get a detection. How small of a leak you'd be able to detect i'm not sure as i don't have the expertise nor field experience to understand the sensitivity. At the minimum it gives me some reassurance along with a bubble test and should I have a non line set leak hopefully I can detect it and use it for evidence of a defective unit to the manufacturer.

I am not an HVAC professional but a home owner with ongoing AC issues and when I saw that I could get a device like this for this price range, I felt it was a good investment. And I was right. I have had to refill my upstairs AC unit 2 times now, each time it cost me about 700 dollars. Each time the repair man tells me he found a small leak and fixed it, but then a month later I have no AC again. I was able to use this device with some basic reading (instructions are good for a layperson) and spend the time my repair man wasn't willing/able to spend to find the actual leak(s). I followed the entire run and found 2 other locations that were slowly leaking refrigerant. I called him back out and he has now done a 3rd refill of the system after patching the 2 locations I found. So far it seems good. I have checked several times and no alarms have triggered. The AC continues to run. This makes me believe this devices is well worth the investment if you live in a place where AC is mandatory (like I do). It comes with a nice little case to keep it safe and its small so can be stored away without taking a lot of space. I don't know about the other uses it lists but it appears to be a very versatile tool that can be used to detect a lot of different refrigerants. Don't know how it would be for a professional HVAC person but for a home owner/DIY level use its more than enough and affordable.

Built well, easy to use, very intuitive.Comes with a soft case which is perfect for protection, storage, and travel.It covers most refrigerants, so it's easier to list what it DOESN'T cover, which is basically 3 classes of refrigerants:1) Propane (R-290) is moderately common:Residential - sometimes found in window units.Automotive - not usedCommercial - sometimes for small applications, not HVAC2) Isobutane (R-600a) is pretty common, mostly for fridges:Residential - mostly fridgesAutomotive - not usedCommercial - rare3) Carbon Dioxide (CO2 or R-744) - a newer form of refrigerant, growing number of usesResidential - heat pump water heaters, maybe in HVACs in the futureAutomotive - growing use, particularly in EVsCommercial - common in refrigerated truc:ks, commercial and restaurant sized fridges, heat pumps, supermarket freezers and refrigeration*both Propane and Isobutane are in the Hydrocarbon class.And now a list of what it DOES detect:1) CFC's - primarily residential HVAC, pretty rare, they're mostly phased out:R11, R12, R13, R502, R503, etc.2) HCFCs - primarily residential HVAC, slightly more common than CFCs, but also phased out:R22, R123, R141b, R402a, etc.3) HFC's - very common, residential and automotive:R134a, R410A, R407C, R417A, etc.4) HFOs - very common, newer automotive, chillers, wine refrigerators, commercial refrigeration:R-1234YF, R-1234ZE5) Freon - brand name from Dupont, rare, phased out though you may still find it in older automotive, commercial, &/or residential applications:R-12, R-22, R-5026) Halogens - everything above (fluorine, chlorine, or bromine) falls under the class of halogens, though there may be more halogenated gases not listed above7) Perfluorocarbons (PFC's) - pretty rare, found in old aerosol cans, used in the semiconductor industry, might be blended with other refrigerants to make sub-zero freezers, it's a pretty niche thing:PFC-14, PFC-116, PFC-218 etc.8) Ammonia (R-717) is commonly found in commercial applications, like ice rinks, beverage industry, food processing, pharmaceutical, cold storage warehouses.Hope this helps!
