    I got around to testing R-22 with my detectors in the back of the garage with the door open and jug on the floor no breeze @ 70˚F

    With the reference leak my SRL2 and SRL8 did not pick up anything and my ZX-1 was screaming again.

    I changed the clean filters on the Fieldpiece units with new clean filters and got the same result -0- leak detected with either Fieldpiece unit.

    I have some R-134A setting up now and will try the R-410A again.

    At least from the videos it appears something is wrong with both SRL2 and SRL8 unless being outside makes that much of a difference compared to inside where you did it Mech.

    At least now I can see why I'm so frustrated with these Fieldpiece detectors but I still not sure if if there is anything wrong with them or not.

    Maybe Russ Harju can address your problem and provide assistance.

    I really don't think anything is "wrong" with them.
    This is my second SRL2 and they both had the same sensitivity IMO
    that's why I never bothered sending it back for a third.

    It is a simple device that is only calibrated for one pressure.
    When connected to something like R-410A or a hot or cold drum of R-XXX it is merely a reference leak but still useful.

    Yep smoke and mirrors
    Thats the only way I could find a small R-410A leak with a heated sensor

    Bacharach Informant II....

    Okay, so I've spent the rest of the summer comparing the sensitivity of this tool between R-22 and R-410a and there is a difference. It picks up the R-22 from quite a ways away (3-5ft). You have to move over the surfaces of the piping system (within 6in.) to detect R-410a but it picks it up right away. In terms of R-22 it picks up concealed leaks (under the insulation and other things) very well. You have to remove the insulation for 410a detection. This is by far the best meter I have ever owned.

    There are 2 quirks that I found with this unit however, if you are in wind or are sniffing near a running fan, you will get false readings.

    Also, the sensitivity scale is much more balanced when detecting R-22. with 410, it's either screaming or it just barely ticks. After getting used to it, I found that you just stay near the tick and get really close and move the tip slowly. You will hit gold pretty quickly.

    99% of the leaks I found this summer were due to poor brazing... Which also means that the systems were not evacuated properly to begin with. Shame, shame....

    Best find of the summer was when I was called out to a new install to find a leak (they couldn't keep the unit running correctly either) and I knew almost immediately that there was a kink somewhere. So, I went to the last place anyone would want to look (the attic) and found a kink under the insulation. The kink has a small tear in the corner. Recovered, repaired, evacuated, recharged and the homeowners were happy little clams.

    I hope I have helped a little and don't come off as the idiot that I was portrayed to be a few pages back.

    I think the guy was just mad that I don't like Fieldpile.. Whatev

    A lot of posts in this thread.

    Ok my problem. They re stucco the building and suspect a staple hit a line inside the wall. Need a way to find the leak area so I only cut one hole in the wall to fix it. Will cut the sheet rock from the inside vs the brand new stucco. The line run's from the attic down 2 stories to the ground.

    I'm thinking a stereoscope. Not sure if an ultra sonic would work inside a wall.
