mail to airtech…
I can ask for a quote on monday.
if we could use a parabolic plate on the end of the detector would it help in any way to get a direction of the leak so we could reduce the surface we have to search?
Thank you very much!
I can supply you with a NEW Sontector WRD-33 for around 1000 euro including shipping…
Good to know, thanks.
Let me think about it for a while.
Keep in mind that I can supply a VacTrac for less than half that price…
On your opinion, is the more expensive worth the extra price?
Everyone has to decide for himself. It is more specific, (pinpoints to 1mm instead of an area of 10mm) but if that is really needed? The unit does feel more sturdy than the Vactrak, which is a bit flimsy.
If you have the money get a hellium leak detector
Wow! 1000-2000€ for used leak detector. I wonder why it so expensive. Is it from titanium? Got mine from Ebay for around 60€.
Since I’m a electronics guy too, I looked about the voodoo behind it. There are basically two different ultrasonic detector technologies. The first one is basically a frequency divider, better versions have a volume restoration, because frequency division is done digitally and destroys the level. With this units you can hear a wide spectrum, but it sounds a little weird.
The second one is called a heterodyne detector and this one mixes the ultrasound with another ultrasonic sine wave. If you have the correct frequencies the mix will generate a audible beat frequency. You can tune this to a specific frequency, but the bandwidth is rather narrow.
Both devices can be built at home with 30-40$ parts. If interested google for “bat detector”.
Can anybody tell me what makes the professional device so much more expensive?
Is there a special feature I’ve overseen?
I am not an electronics guy. I always was under the impression that electronics run on smoke: Once the smoke is out of the tool, it does not function anymore…
What is available on these units is an on/off button, a sensitivity slider, and basicly that is it. Volume is regulated by the headphone. (and for 500-1000 usd you get a rather cheesy one)
Has anyone given the bar detector idea a try?
Hi Herman I saw you can supply the airtech sontector 33 and I’m interested…can you contact me at palesmartino@yahoo.it
used helium leak detector are not badly priced.
I have been using the accutrak leak detector for years and they are great. $350

For any of the electronically minded here, these leak detectors are exceptionally simple circuits. I built mine for a total cost of AUD$17.00. Works like a charm after I worked out the kinks.

The Inificon Whisper I got works well
Hanaldo, which type of circuit did you build? And do you use any special microphone or sound focussing device?
This is my circuit:
No nothing special, I just used a 40kHz transducer. Works very well, and I played with the idea of using a parabolic reflector to increase sensitivity but it really isn’t necessary.
