Elitech Freon Leak Detector Halogen Refrigerant Gas Leak Detector HVAC Tester AC Sniffer R22 R410A R134A 1234YF, WJL-6000S

Excelente dispositivo.Me gusto bastante....Aunque se vea simple....Solo al que saber usarlo....

look good

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.

super easy and good

I dunno what to say. I put it into my ac low side service port and it beeps. I put it next to my water pump it also beeped once lol. Water pump isn’t even close to any ac lines or compressor etc. It does detect Freon as my mechanic sprayed Freon near it in the air and it went off but it also gave false positives by my water pump as if it mistook heat or antifreeze smell for Freon. I don’t know if my ac service port is leaking Freon or not now because of the false positives. I’ll keep it as a toy to help diagnose it but it doesn’t seem as accurate as everyone says. I also turned down the sensitivity button and once I got a beep and once I didn’t by the water pump. I’m gong to try it with the engine cold and see if same thing happens.

This detector perform great on r1234yf gas. its a good product for occasional use and you don't want to spend a lot of money. It also comes with a light that clips on the flexible pipe but I didn't need it.

Would give 0 starts if I could. It says my skin has a freon leak, the air in my house has a freon leak, my girlfriends sweatshirt has a freon leak... but when placed directly over what I know is freon because I watched it spill it only went off 1 of the 2 attempts. It's basically a oversozed mediocre black light. I'd save your money and buy a slightly more expensive one

uv light and sniffer work great together
