I do have that, i have played with it and it did great for parking sensors but you really gotta be close for it pick up an air leak. Iwondered if the booster could be used with it that arduino uses for the piezo? Irecently ordered some I'll betesting itout

I've not used a detector like this - Will it bubble at a refrigerant leak in a fully charged system, or just when you've evac'd the system and pressurize it with Nitrogen?

Yep i know 100 percent that's me, hence i use the soap so much, and visual with a camera. I know I'm too impatient. Which is funny because the soap can take 30 min to show the foam. But i use the h10 leak detector. It's bulky butseems better than the Robbinare wehave

The link opens to his use of an ultrasonic leak detector videos. He shows how other noises can interfere. And from what I've seen, he usually verifies his found leaks with bubbles or dye… As for bubbles, I buy this by the gallon, dilute to suit your needs, and as Glenn mentioned, patients. Great for tiny leaks, bubbles don't lie :O) Evap cores are a different matter…

I use the leak dye detector thing from Snap-on. It detects the hydrocarbons or whatever from the gas for our 134 AR 1234YF that thing has been a lifesaver. I can find leaks within two minutes of the thing powering on and heating up.

Yea. I've seen a few of his. None with ultrasonic though. He knows so much. Really does show the need for specialization.

I use high concentration soap and nitrogen setup for leaks. But with evap core that's a little tricky, I've gotten good luck with my camera and dye but I had a Volvo recently had extremely limited access to the core. I've never used one, and I did research arduino a long time ago so I have very little understanding on this so my question is these work like sonar correct so using them for evap cores wouldn't really work given the pieces of the box and curves would give a false sense of air. Or am I thinking wrong on how these work? And if they work maybe by picking up frequency of the air noise does any one know what that would be to maybe have a little project. And yes I am one who would spend the same amount of money playing with the electronics to fail thn espend the money on a tool that mightwork
