    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.

    I have an Accutrac ultrasonic and it is great, I use it for leaks that are hard to pin point, motor bearings, saddle bearing, you name it, I also have the D tek Stratus, select and tec mate for leak detection, I have found many leaks using all of them.
    I hope this helps you.

    I have the Bacharach model bought off tru tech. I bought the model with the nice head phones.

    Found a couple leaks so far. The ones I found im confident I would of found with my field piece heated diode as they were not very small leaks.

    There is definitly a learning curve to differentiate the noise that is made from a leak vs the noise made from rubbing against something. It is more like a scratching static noise.

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.

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.
    When I was in Electronics School, we had to build our own meter from a kit, and it had to work, and it was what we used to do our final project. This said, if your meter didn't work, well obviously, you lost points on it as well as the final project, and you probably still graduated, but when the companies came to hire, they would always ask, "Who's meter worked? We'll talk to them first" The reason I added 3 quotes to this one reply, I am sure I could put something together, but like it has been stated, these BIG companies have guys employed, or buy the engineering from someone else, the other thing is, they have "Proprietary" parts, and while yes, you can figure it out, and this one part will work, and you can make 2 or 3 different parts do what the one part does, it can add distortion, or some other effect that can only be seen on an oscilloscope and will not be as "Scukum" as that shiny made brand name thing, but also, it may even work better, since a lot of them will take shortcuts on some things, but who, in this business we are in, actually has the time, and considering, I did use my meter, which I made for about 6 years, when it failed, I bought the Fluke comparable meter, which was "True RMS" and was more accurate than the kit I built meter. Now onto this type of thing, we did build one in lab, and it worked, the lab instructor was a former Marine and told us, this would come in handy, Oh I almost forgot, our final project was a box, which did contain an ultrasonic listening device, as well as a few other things and bread boards to build test circuits etc. and I did use it to find refrigeration leaks for a while, till it got thrown out by my ex-wife, and the circuit that was used for the ultra sonic listening device, we covered and it made sense at the time and wouldn't find all of the leaks at the time and it was about as accurate as big blue, it also would test motors and compressors(which had a motor in it) So it is possible, but not really practical, unless you start with a prototype, and improve on it, research and rebuild and test, but like I said, who has that kind of time in this business, I guess I wish I had the time, but in reality, if I did, I would probably be crafting some wood project, like a real wood bookshelf, with all hand made trim etc. and end up giving it away to someone, since you can never sell it for what it takes to make, but when you see someone you know or care about smile at the item you made with your own hands, it gives you a good feeling inside.

    Safebustr, good luck on building it, take your time and do some research and I am sure you will need an oscilloscope to fine toon the circuits that make it work, also, they will change over time through use and will need to be put back into tolerance from time to time and some components replaced.

    Thanks for the encouragement. I have been working on my circuit a little and so far have only built one portion of the project. I do own an oscilloscope and several other pieces of test equipment including a powered breadboard which comes in real handy wiring up circuits to try.
    I think I will end up building the ultrasonic source first so I can have a sound source to search for.
    As for having the time to play around with this project, I am retired and only do HVAC on properties that I own and maintain. I have three properties in NC and several here in SC that I look after, about 14 systems total, so I don't make my living doing HVAC, I also do some plumbing and electrical on all these properties.
    Mostly now just admire God's beauty on the beach, do a little metal detecting and enjoy playing with my tractor back on the farm in NC.
    Progress reports to follow.
