WJL-6000

Works like a champ. No issues.

This device is works great and is very inexpensive. As I was using it I noticed that it would pick up the smallest traces of refrigerant. It came with batteries and was pretty easy to use.

So I thought the unit didn't work but it turned out I had 1 of the 4 batteries in backwards. My bad. Amazingly the unit still blinks the LED mostly green even with one of the batteries backwards, just doesn't detect refrigerant.With the batteries properly installed I can spray a small burst of HFC 152a into a cabinet and then the probe detects the refrigerant whenever it's brought near the cabinet. Though after about a minute the refrigerant has dissipated enough that it can no longer be detected (in a mostly closed cabinet) so the sensitivity may not be as high as advertised.original 1 star review*The unit doesn't wnework. The unit powers up properly with the green LED blinking. But there is no change when exposed to refrigerant, even spraying HFC 152a directly at the probe. Tested it outside with no refrigerant and also in the garage, spraying HFC 152a, at different sensitivity levels. Same blinking and beeping in all cases. Possibly it's just a bad unit. I may try another one and if that works I'll update this review.

Had this for 10 years. It still works better than my field piece infrared detector.

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.

Works great detects a leak I’ve had for some time able to fix and then recheck for no leak.

I bought an earlier version of this detector a few years back. At the time I used it to help detect a leaking Schraeder valve on my truck. It detected the leak at the time and there was great happiness in the land.Fast forward to this afternoon, when I tried to use the detector to check for leaks on my car. My AC slowly gave out on the way home and I was sure it was a leak, but I didn't know where.Fresh set of batteries (I don't keep batteries in any of my tools if I can help it), turn it on, and it IMMEDIATELY starts to alarm no matter where the sensitivity knob is set. I turn it off and on again but it does this 2-3 more times. Finally I shut it off and turn it back on, and it reacts normally, IE no false alarms.Of course, now I don't trust it. I put the probe near the low-side port on my car's AC system and blip the Schrader valve just enough to release a tiny burst of refrigerant. The detector does not detect anything. I do this 2-3 more times, turning the power off and back on between attempts. The detector never so much as caught a whiff of the escaping refrigerant, no matter where the sensitivity knob is set. It should, considering it's designed to detect leaks much tinier than the artificial ones I was creating.So, I'm out 20ish bucks because the detector went straight into the trash can. I bought this thing based on excellent reviews and price, but I think next time around I'm going to spend a little more and get something I can trust a couple of years down the line. Unless you're on a really tight budget, I suggest you do the same.

Working very well. Satisfied with this product. Also like the added light because I had an older version which I didn't get the light.

Accurate work best quality
