  • Simple to use, inexpensive, and works.
Color: WJL-6000
I ordered this product at the beginning of an auto AC DIY project that went on for months, and didn't get around to actually using it for awhile, but by the time I did, I found that it worked great, and was well worth the price I paid for it. Specifically, it helped me confirm that the valves on both high and low AC service ports were leaking, and that I needed to replace the cores in both valves. It subsequently helped me to confirm that my core replacements worked, and sealed the leaks I was previously detecting. Both the detection and sensitivity functions worked fine for me, and they should for you too, as long as you follow the instructions and don't expect this simple gizmo to perform like some kind of lab grade precision tool. When searching for leaks in unknown locations, the instructions suggest starting with the highest sensitivity level, then gradually decreasing it until you've pinpointed the exact location of the leak. I did the opposite, because I was testing for leakage from two known locations (AC service port valves) ... in other words, I started with the lowest sensitivity, put the tip as close to the valve opening as I could without touching it, and then worked my way up to gauge the severity of the leak. I got a few false alarms in ambient air at the highest sensitivity setting (knob turned until stopped), but wasn't upset about that. Just turned off to clear/reset the internal electronics, started the sequence again at a slightly lower sensitivity setting, and it worked fine. No false alarms when I backed the knob off a little from max rotation, which I see as "normal" for a simple device like this. For example, the control knob just isn't that sophisticated ... it's the same as a combination power/volume control dial on a radio, which probably gets pretty sketchy when it's controlling the "sensitivity" of something as delicate as an electronic gas detecting sensor. This is a BASIC refrigerant leak detector that worked as advertised for me, for a very reasonable cost. Very satisfied. ... show more

  • What a cool little tool. Cheap and accurate when used correctly! What a cool little tool. Cheap and accurate when used correctly!
Color: WJL-6000
I've been struggling to find a tiny leak in my HVAC system. Dye (Twice) with leak sealer failed to seal the leak and it was nowhere to be found for over a month. I decided to take a chance and get this "sniffer" to help locate the leak. Reading the reviews i was a little worried since many people stated it does not work. but after careful research and understanding that the sniffing tip of the unit is ultra-sensitive, I ended up purchasing it anyways thinking i will be very gentle with it. The tool showed up the next day, I put batteries in the unit and activate it and it seemed to perform the initial startup properly. I went to the outside unit (which I already had completely open) and started moving the probe 1/2"-1" from any object but following the copper lines, i went near every soldering point and nothing... I thought for sure the unit is not working. I went back inside and took apart the air handler cover and started following the copper lines and in 5 seconds, the tested start beeping fast as I came close to one of the valves inside the air handler. I then turned the unit off and waited a few seconds to have the air remove any leftover halogen from the tip and started it up again and went in the direction of the same area and again it started beeping. I confirmed that the leak was there by spraying some water with dish soap in it to make bubbles and BINGO! I tightened up that nut and verified with bubbles AND the sniffer that the leak was gone. All in all, the unit performed perfectly when you use it gently and I performed the test multiple times after allowing it to sit unused for a few minutes between tests. ... show more

  • Easy to use, arrived on time.

It seems to work well, very easy to use. I did not find my leak, but was able to test it by creating a very small leak which it detected easily.

  • They actually work great, and come with a blacklight They actually work great, and come with a blacklight
Color: WJL-6000
These things are great and well worth $25 if you are a "do it yourselfer". This is the second one I bought, because the first is in another state. The beeper will find freon, even on R1234yf, as I tested it with the can. It found the leak on my R134 on my Toyota last year. And, using the blacklight, just found the leak on my GMC Sierra, which comes precharged with fluorescent dye. (below) Didn't expect much for the cost, but they really work. ... show more

  • Hyper sensitive
Color: WJL-6000
After reading reviews where people said it didn't work on obvious leaks (like open cans of refrigerant), I was hesitant to buy this. But I really needed to find a leak so I took the plunge. My issue is the exact opposite; no matter how low I dialed the setting, it triggered the alarm. It looked like every one of my fittings was leaking. I thought I had at least enough competency to get at least ONE of the fittings right so I immediately became suspect. I had the system evacuated and hooked up my air compressor to fill it full of air. Then got out a spray bottle with some water and dishwasher soap and started spraying fittings. After a few minutes, it was clear I had a leaking Schrader valve on the high pressure side as it was bubbling. So I replaced that and put it under vacuum a week ago; no leaks so far. I think this is a nice item and the price point can't be beat but it just didn't work for me. ... show more

Complete junk. There's no fan internally to pull the freon into the sensor, I sprayed freon directly on the unit of three different types. It never once picked up anything. All it does is beep when you turn it on.Don't waste your money.
