This wiki has been updated 16 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 choices, we may earn commissions to help fund the Wiki. If you'd like to contribute your own research to the Wiki, please get started by reviewing this introductory video.

Editor's Notes

April 08, 2019:

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.

After getting his bachelor’s from the University of Texas, Quincy Miller moved out to Los Angeles, where he soon found work as a copywriter and researcher, specializing in health and wellness topics for a major online media brand. Quincy is also knowledgeable about home improvement, as he’s had extensive experience with everything from insulation to power tools to emergency room trips, sometimes in that order. Sharing a home with three dogs and a couple of cats has forced Quincy to learn as much as he can about pet supplies, animal nutrition and, most importantly, the best ways to tackle the mountains of fur that accumulate in every corner of your home.
