Refrigerant Freon Leak Detector with Indicator Light, High Accuracy and Halogen Gas Leakage Tester for HFCs CFCs CFCs Halogen R134a R410a R22a Air Condition HVAC

Very sensitive, on high sensitivity will detect traces on the high and low ports. But can be dialed to avoid that. Seems to be working fine. Triggers when close to leak.cant ask for more for the price.

Worked great first use now buzzer doesn't sound off. It's very hard to see the led in broad daylight so the tool has become ineffective. No manufacturer listed in manual or what to do when in need of warranty or service. Besides saying 1 year warranty and no charge repair replacement with no way to process it. I can return to Amazon but price went up so I would have to gamble more $$ to try again. Anyone have an email address or a link for replacement?I will update review if somebody reaches out.5/22 seller responded, asked some questions and is sending a replacement. So far so good. It doesn't matter who makes your tool, what matters is accuracy, reliability and warranty. I have had high end diagnostic tools fail and if the support is there it's a good investment.12/17/22 using it again today and the replacement leak detector is working great. Found the leak pretty quick!

Have several leak directors purchased this one because of reviews and it works great .Great value highly recommend

Bought this as a long shot to find an on going ac leak.After only 5 minutes of moving the detectors around ac components it started faster beeps around the high pressure port.I had installed the Dorman brass fitting in the port to prevent leaking, so i was baffled.Sprayed some soapy water on the port, and it was bubbling from the outside casing of the port. A small crack could be seen. Leak was not from the inside ball valve.Ordered a new high pressure port, hopefully the end of leaks. 2000 Astro van.But if i had first used soapy water to check for leaks, i wouldn't have needed this sniffer.Update- high pressure service valve was not cracked. Leak was coming from o'ring. Was able to tighten high side valve- no more bubbles. Lucked out on the fix. Smiles.

The product was able to find an A/C leak within 5 minutes of using for the first time. Excellent value for money.

I tried this leak detector several times, but it did not work! My neighbor has a higher end leak detector and it found the leak quickly. After locating the leak, I took this leak detector and put the sensor probe right at the leak. It still didn’t pick up on the leak. I was using brand new Duracell batteries too. You are better off taking your money and setting it on fire! At least you will see something!
