    Question

    I have been searching for the Holy Grail in leak detectors.
    I believe there is no single, sure fire item. I have seen soap fail, I have even seen a condenser (small one)cut out and pressured up to 200 psi and dropped in water, not leak at that time. Dyes and electronic detectors have missed at times also.
    So, I am looking at adding an ultra-sonic to my bag of tricks.

    What brands do some of you use? and why?

    Thanks for your input, it is appreciated.

    Yuma,
    What is snow? Is it that white stuff in a freezer?

    Some years ago I borrowed an ultrasonic from a co-worker. I found the leak within minutes after my soap and sniffer failed to do the trick. I bought one the next day. Now most of our techs either have one or want one. I have the
    AccuTrak VPE and highly recommend it. I have also used the one that Amprobe makes but didn't like it as much as the AccuTrak.
    Even a fish wouldn't get into trouble if he kept his mouth shut.

    This is really odd. I've heard people here saying they found leaks with ultrasonics, but I've got one laying out in the garage, and it wouldn't find a leak even if my dog peed on it.

    Is there some special, magical technique to using one?

    There's a guy at work that can hear better than the US . They have only been usefull for larger leaks when the area is contaminated with freon , in my experience.

    I have the same question.

    What has been effective is isolating the lineset/evaportator from the condenser then jacking the lineset/evap with nitro and watch for a pressure drop if you don't hear it hissing.

    I would give the ultra sonic only one thumb up. It tends to miss leaks on welds but finds them on fittings if the leak is large enough. One thing good about the ultasonic is that they are FUN to use. It was a great little toy. Just put on the headset and walk around with the probe. Makes the customer think you are really hitech.

    Thumbs up UltraSonic Huh?

    I got mine about a year and a half ago and it is my goto leak searching tool. I have found leaks that other methods have missed. I have also had a few I couldn't find with it but, wind will cause trouble with an ultrasonic. The biggest thing you must do when using one is learn what to listen to. I have found leaks that have made some rather peculiar sounds. If I was listening for just a "hiss" of escaping gas, I'd never have found several of the leaks I was looking for.
    I've let some of our apprentices use it to search for leaks when they are training with me and they all grab it first when they know we're leak searching, even though I also have nitrogen and soapy stuff, an electronic "sniffer" and a halide torch. It's the first thing anyone grabs for leak looking.
    I've recommended one of these to all the techs where I work and to the bosses if they should find it in their hearts to get one for the techs.
    I have a kit by AMPROBE that has the detector and headset, a parabolic dish, a snoot and tube and a transmitter for use in tanks and large, enclosed areas. It was sorta pricey but, It's made up for its cost quickly.
    If you decide to invest in one, take the time to learn how to use it properly and effectively. You'll not regret it!

    These responses shock me.

    I continue to be impressed with the performance of the Accutrak. This thing flat works! Everyone that borrows mine ends up buying one or asking for it again.

    How is it around a noisy compressor and fan motor or do you use it with just static pressure?
    We've been doing so much,for so long,with so little, that now we can do almost anything, with nothing at all.

    I use ultra-sonic, electronic and Blue something for bubble check. Each one has a unique way of finding a leak but not one of them is perfect I have found. But I always end up using bubbles as the final location check.

    Ultra can also be use for bearing, vibrations, just about anything that moves. I have also used it in noisy machine rooms looking for pneumatic control leaks in lines and controllers. Works great.

    Just not too fun when one of your work buddies taps it with a screw driver.

    Since they only hear ultrasonic sounds everything else is muted. The first time that I used one was on a rooftop with 7 35ton compressors running. The leak was picked up loud and clear. Big Blue enhances the effect. I bought one the next day and use it as my primary leak checker now. It also came with a contact probe to listed to bearings and internals. And since it is ultrasonic you can also use it to check for leaks when under a vacuum.

    The KTM is SWEET! The more miles I get on it the better it runs.

    How's the KLX? BTW, I have a shop manual, a new twin air filter and a new spark plug. Spares that were never used and I no longer need. Let me know if you are interested.
