Elitech Refrigerant Leak Detector AC Freon Leak Sniffer R22 R410A R134A R1234YF, WJL-6000S (5PCS)

I have a R410A a/c system. This unit was able to find the leak in less than 30 seconds. I love it. It's inexpensive. But it works.

I really love this. Just what I needed for work.

Working as expected

The media could not be loaded. This sniffer is very sensitive. I am impressed at how well such a low-cost device is working. I was able to pinpoint a leak coming from the side cap on my expansion valve. As shown in the video, the four o-ring pipe connections are fine, but a leak on the far side of the valve is detected. To confirm, I put a bubble solution there and could hear & see the bubbles. There were no false alarms, but remember that refrigerant vapor is heaver than air, so it will tend to settle downward. This can cause the sniffer to alarm when you are below the actual leak.

All it does is beep it found nothing and is very annoying it speeds up and slows doown in the same spots and beeps fast for water. I gotta stop just buying anything and everything hoping its not a gimmick.

Bought two of them and one is not working need to return it and get another one have not heard from anybody

Worked! found my leak in less than a minute

The media could not be loaded. It work the first one I got was broken. They did the right thing had a new one next day.
