The 6 Best Ultrasonic Leak Detectors
This wiki has been updated 15 times since it was first published in December of 2016. Nothing can bring an engine or HVAC unit screeching to a halt quite like an air or fluid leak. Unfortunately, finding one can be a lot like searching for a needle in a haystack, since the sound made is tough to hear. These ultrasonic detectors take some of the guesswork and pain out of diagnosing a fault, as they can pick up on noises beyond the reach of human ears. When users buy our independently chosen editorial recommendations, we may earn commissions to help fund the Wiki. Skip to the best ultrasonic leak detector on Amazon.

While the selections on this list are all quality options, that doesn't necessarily mean that they're all equally suitable for whatever task you have at hand. For example, the Robinair 16455 TruTrack is ideal for HVAC technicians, whereas mechanics in busy garages may prefer the Amprobe ULD-300.
Some models come with their own headsets, like the Inficon Whisper, while others require you to purchase your own. Which one is preferable for you is a decision we can't make; some people will want to upgrade the basic models that come with the devices, while others will be more than happy to deal with a little less comfort and inferior sound quality in exchange for more money in their pockets. It's completely up to you, so long as you can still hear clearly, whichever one you choose.
