WJL-6000 Freon Leak Detector Halogen Leak Detector Refrigerant Gas Leakage Tester HVAC Air Condition R22 R410A R134A CFCs HCFCs HFCs Detects High Accuracy

Accurate work best quality

No good product very low quality

This product not detect any gas ....for testing you hold on wood, iron, copper & your finger it will beep.....very bad product. Do'nt buy this.

It's a defective item, it's not working. Pls replace this.

Don't bay

Its leak or not beep sound not fount any leakage its very bad product i buy this product but not detect any leak cheating

Good useful advice

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.

conforme aux conforme aux attentes m'a permit de détecter une fuite sur la valve

Envio rapido, bien envuelto. Lo utilizo en automocion, y va de lujo. Buena sensibilidad

Sirve muy bien detectando fugas,Gracias
