    Ultrasonic leak detector

    Any one had any luck with the ultrasonic type leak detector?
    I am considering building one to try out and see what I think. Looking at the commercial ones and the price tag, I feel I can kluge up something that will work for lots less money. Any one else ever tried this?
    I have many years working on electronic equipment and have built lots of stuff over the years so the challenge might be worth a try. But then again my junk box is full of half finished projects that I lost interest in before finishing.....
    We shall see.

    I have good luck with my ultrasonic leak detector.I have the Whisperaire,made by Inficon.It is not too expensive(About $300.00) compared to other brands.I would like to try one of the more expensive ones,like Bachrach ,to see how much better it is.I have found a lot of leaks with the WhisperAire.

    I bought both the amprobe and the accutrak so I could compare them. I created a very small leak I could fine tune and the accutrak was able to hear leaks the amprobe could not. The hardware on them is probably simple but the firmware probably isn't. There is something about the accutrak that makes it better. I love it...Ive clearly heard leaks that are so small you can barely see microscopic bubbles when you spray the big blu. There's a learning curve for sure but it's worth it!

    The Accutrak is probably better than the WhisperAire.It should be, it costs more.The Accutrak may be on my bucket list.Which Accutrak do you have/s far as electronic ,I think the D-tek Select and the new Stratus are very good.I have a D-Tek status.Still waiting to hear a comparison between the Stratus and H10!!Who sells the Accutrak,I don't see it sold in anybof the parts houses that I go too ? Good to know, not to buy the Amprobe.

    I've got the gooseneck version that I bought off zoro with a coupon (they always are running sales). Accutrack is made in usa too...a rare thing for sure!

    I don't have any Ultrasonic unit yet, What got me interested in them was a advertisement I got from Accutrack the other day. I really liked the unit until I got to the price.
    I still might pull the trigger on one but thought I might try a homebrew one first. I am sure it wouldn't be as good as the factory job though.
    I have the D-Tek Select and like it ok but the ultrasonic unit looks interesting.

    They are all good to have. One will not replace the other IMO

    I imagine, if you have the skillset to build something like an ultrasonic listening device, go for it, if nothing else, you'll know if it works or not and you could always drop back and punt and buy a name brand device.

    I do have a degree in Electronics and I imagine I could build one after doing a fair amount of research on what and how, but the shiny package that comes with the fancy store bought product, just cant be replicated on any level thats close to that! LOL I mean, that has to count for something, right?

    I've wanted to make one of those ultrasonic speakers they sell or whatever the correct term would be. That can't be too hard.

    You know what a good one costs, so if you come up with something equivalent, perhaps you should make to sell?

    I'm in the market for one. :-)

    Electronics is a hobby of mine as well and in a lot of cases I don't feel like diy versions are worth the time and money...yeah they may work and be a lot cheaper but amprobe has some very high level engineers working for them and if accutrak is even better than that, I don't think a home brew stands much of a chance. Yeah it may work, but if you don't trust your tool to find small leaks you'll never get it out. I know I can trust the accutrak...that goes a long way.

    Im positive I can build one but also certain that it won't be as pretty or function as well. I have been researching the circuit and have ordered some parts I didn't have like the ultrasonic transducer. Several companies sell products that may be the basic circuit that I start from. One such idea is a ultrasonic power line arc detector. I found the circuit for it in an old QST (amateur radio )magazine and further research found a company that makes a commercial version that has the same basic circuit.
    I think my first prototype will be that circuit and if it works I plan on adding the other embellishments such as the bar graph display like the Accutrack has. I won't be trying to build any to sell even if it works great.
    I would like to actually look at the guts of the commercial job to see how they did it. I'm willing to bet it isn't as complicated as we think. I did find a research paper from an electrical engineering student that built a super version but it's way more complicated than I want to tackle. Stay tuned for further episodes.

    I have a D-Tek Select and a Stratus,they work good but never had an H10Pro Thinking about getting th H10 pro soon,But not certain how much better it will be than the Stratus.They are both rated high.I do have a Ultrasonic WhisperAire(ultrasonic) I fond leaks with to.I'm thinking H10 pro next.This summer.MaybeAccutrak for my own Christmas present.

    Any one have a Bachrach Ultra Sonic Leak Detector?I'm looking on the Trutech site ,They have the Bachrach version.It looks very similar to the Accutrak,but a little less money.Curious,Anyone used this ultrasonic from Bachrach.Bachrach usually has good products.

    Accutrac made some improvements within the last couple of years. I'd would make sure it's the latest and greatest version first.

    AccuTrac makes the Bacharach unit.
    FYI
    TruTechTools moves thru inventory so quickly that what we sell is the latest, as a general rule.

    To TruTech Bill:Interesting enough ,I thought the bacharach and Accutrak looked the same and was about to ask if Accutrak made the ultrasonic for Bachrach.Now I know that they do.However,the same version in a Bachrach is cheaper than the Accutrak version!!!!Which version do you sell the most off, and recommend?

    Maybe there is a way to check serial numbers if you call AccuTrack or if they are putting different parts in the different labeling.
